hydroking68 Posted April 26, 2010 Report Share Posted April 26, 2010 so i got a newer motor for my 510 and it ran with the old one till it blew up got another L16 and get it in and nothing so i changed out the ignbax ond coil cap rotter and still nothing i got power to every thang but still nothing any help thanks Quote Link to comment
izzo Posted April 26, 2010 Report Share Posted April 26, 2010 check the coil wire going from coil to dizzy. Pull it off the dizzy and check for spark, if so, then pull a plug wire off and check it. if u got spark start checking other stuff. Did you hear the other motor run before you got it in there? Check timing, check make sure oil drive for dizzy is in there, set TDC and make sure oil drive is set right etc.... i kno it sounds stupid but if u got spark and timing looks ok, make sure you're getting gas and the gas lines are tight with a hose clamp or something. When we got the motor back in my truck it wouldnt start, i forgot to put 1 hose clamp on the gas line :rofl: Quote Link to comment
78kingcab Posted April 26, 2010 Report Share Posted April 26, 2010 izzo its my old l16 so the motor has everything...and ran next to perfect....its gotta be electical....it had a el dizzy but he put a points dizzy in.....by the way hydro you can have the clip to go to it....keep us updated so we can get ya going ...i need your # again......if it ends up being a bad coil let me know i got a new in box you can have...

hydroking68 Posted April 26, 2010 Author Report Share Posted April 26, 2010 hay cory my #661)886-0506 hit me up cuz i need some help lookin at her i left the dizzy that was on the motor so its not the points thang any one els whats to hit me up the #is here so thanks to all for the help Quote Link to comment
78kingcab Posted April 26, 2010 Report Share Posted April 26, 2010 oh so its how it was .....damn...and the coil is good?.....is it getting spark....? Quote Link to comment
hydroking68 Posted April 26, 2010 Author Report Share Posted April 26, 2010 yup i changed the ingbox and still no spark i got a spark tester for it and nothing idk some one help going crazy changed all the stuff coil ignbox an rotor an cap Quote Link to comment
datzenmike Posted April 26, 2010 Report Share Posted April 26, 2010 Not following this at all. So does it have an EI distributor or does it have a points distributor in it now?????????? If EI it should be wired up this way: Quote Link to comment
metalmonkey47 Posted April 26, 2010 Report Share Posted April 26, 2010 If you put a ponts distributor on it, make sure the points are opening and closing properly. I wasn't getting any spark from my motorcycle for the longest time and i had not clue why until I checked the points :P Quote Link to comment
DISLEXICDIME Posted April 26, 2010 Report Share Posted April 26, 2010 you cant run a points coil with a el distributor Quote Link to comment
hydroking68 Posted April 26, 2010 Author Report Share Posted April 26, 2010 iv got ei and that might be the prob is the coil cuz i got one for the car not the motor so all chang that if is it all keep ya all posted thanks for all the help every one Quote Link to comment
fisch Posted April 26, 2010 Report Share Posted April 26, 2010 Hmmm I don't know a lot, but did you leave the ballast resistor in place between the coil and the EI dist? I don't think you need one with the EI at all. And I was told to get the coil that says it is for electric ignition. Though I hear they will run for a while with the stock coil if the resistor is removed... I think? Quote Link to comment
banzai510(hainz) Posted April 26, 2010 Report Share Posted April 26, 2010 I thought I was bad!!!!!!!! I cant understand anything hes saying!!!!!!!!!! take center coil wire off dizzy and place near ground and start car. see if sparks. Dont need a spark tester(is there such a thing). if you get spark then its a timming issue of the rotor dizzy timming plate adjustment or oil spindal. If NO spark. Theh see if the power wire is getting 12volts with key ON. Then see if the Hot start wire is getting 12volts in start position. if you have these then car will run. near the end of this is how to install a dizzy, watch it. http://www.guba.com/watch/3000024223/Hainz-Datsun-L-Series-Engine-01-Timing-Tare-down-and-Rebuild Quote Link to comment
datzenmike Posted April 26, 2010 Report Share Posted April 26, 2010 Not following this at all. I thought I was bad!!!!!!!! I cant understand anything hes saying!!!!!!!!!! No shit. But it makes it more interesting to solve the problem. Quote Link to comment
mklotz70 Posted April 26, 2010 Report Share Posted April 26, 2010 so who's got a link to the long troubleshooting posts I've put up for people before......I have no desire to type it all in again!! :) Quote Link to comment
78kingcab Posted April 26, 2010 Report Share Posted April 26, 2010 hydro if you need, come take coil off of my dime...it ran when pulled so i wouldnt touch the timming or anything....it has to be coil or power. 2 Quote Link to comment
datzenmike Posted April 26, 2010 Report Share Posted April 26, 2010 Likely wired wrong. Stuff doesn't go bad from a motor swap. Quote Link to comment
RadioLobo Posted April 27, 2010 Report Share Posted April 27, 2010 I had a very similar problem with my 510 when i switched to the el dizzy. i had no spark at the spark plug end and thought it was the dizzy, checked the coil plug like hainz said and found out that there was also no spark. Jefes de jefes came over and assured me that my wiring was all right so he checked the power at the coil and with the key in the ON position it read 12 volts but when we tried to crank the engine it would drop to zero. Told me it was the ignition switch, so i got a new one and that fixed my problem. Quote Link to comment
metalmonkey47 Posted April 27, 2010 Report Share Posted April 27, 2010 Hmmm I don't know a lot, but did you leave the ballast resistor in place between the coil and the EI dist? I don't think you need one with the EI at all. And I was told to get the coil that says it is for electric ignition. Though I hear they will run for a while with the stock coil if the resistor is removed... I think? I spoke to an MSD tech after wiring up my Blaster 3 coil and was told that even though it's not a point style, it's still a stock ignition so running a with no ballast resistor can prove fatal to some parks. Not sure if this is correct though, since my wiring diagram for the ignition shows that it has a ballast resistor pre-installed by nissan. Quote Link to comment
mklotz70 Posted April 27, 2010 Report Share Posted April 27, 2010 The ballast resistor in a points ignition is there to protect both the coil and the points. The resistor drops the voltage down to about 6-8 so that the points don't arc and the coil doesn't over heat. The coil design is left over from the days of 6 volt setups and doesn't like a constant 12v. Because of the voltage drop the system experiences when you crank the starter, the ballast is bypassed when the key is in the start position and left in the circuit in the run position. If you put an EI dizzy in and leave the points coil, you can a new constant 12v wire to the dizzy(it needs a power wire which the points dizzy didn't), but the coil still needs the ballast. If you leave the points and put in an EI dizzy(which has it's resistance built into the coil), you still need to keep the ballast to protect the points. This isn't a very good scenario since the coil will not be getting a full 12v. Keep in mind that there are ignition setups that don't have a ballast resistor, but a resistance wire connected to the coil. This is still an external resistance to the coil, so it's not the best coil to run. If you use an ohmmeter to measure the resistance from the neg term to the tower term(where the coil wire to the dizzy goes), you should read approx 3-4 ohms. That should be an EI dizzy that does not need the external resistance. If you read about 1.5 or less, that indicates that it's a points dizzy and needs an external ballast. Anyway....that's the boring coil info for the day. I typically troubleshoot the ign sys with a test light. It's by far the fastest, easiest way to do it!! I'm also not understanding exactly what you've changed out. What is the ignbox you're talking about? The matchbox on the side of the dizzy? What do you have on the eng right now....a points dizzy, or an EI dizzy(matchbox or remote ignitor box?) Quote Link to comment
78kingcab Posted April 27, 2010 Report Share Posted April 27, 2010 wow this is real good info i myself did not even know there was a differnce in coils at all... though im not the brightest color in the box.. :unsure: hydro any update on this ....and you really need to clareafy everything these guys are here to help you ....and will.. :D like i said if you need you can come snag the coil ans whatever you need off my dime ..it is exactly how it was when pulled....

hydroking68 Posted April 27, 2010 Author Report Share Posted April 27, 2010 now iv got a matchbox on my dime and power to every thang and still no spark iv dun eveythang that has been posted can any one help me out and get her running im at my whitz end HELP Quote Link to comment
izzo Posted April 27, 2010 Report Share Posted April 27, 2010 now iv got a matchbox on my dime and power to every thang and still no spark iv dun eveythang that has been posted can any one help me out and get her running im at my whitz end HELP Still no spark??? You put a light tester to the positive side of the coil and make sure you have power? Pull the coil wire off the dizzy and see if theirs spark. If not, try and run a hot wire from battery to positive side of coil and see if she pushes some spark then. Quote Link to comment
MicroMachinery Posted April 27, 2010 Report Share Posted April 27, 2010 One of you guys for Portland or Vantucky should be able to help this guy get movin'. If it weren't an hour drive for me, I'd come help ya out man. Quote Link to comment
hydroking68 Posted April 27, 2010 Author Report Share Posted April 27, 2010 ran hot wire and still nothing need fresh set of eyes on her to see what im missing Quote Link to comment
banzai510(hainz) Posted April 28, 2010 Report Share Posted April 28, 2010 So you got 12volts at the + side coil. I assume since you have a Matchbox , you are NOT using the ballast resisitor. You should get 12volt with Key ON. I dont know the wire colors on a 68 myself but there should be a HOT START wire also. which is 12volt ONLY with key in START position. Most people short this and the 12volt ON wire(above together). all you got ot do to ck out this coil is put key to ON youll have 12volts at + side of coil. then take a wire hook it up to the - side of coil. Take Coil wire thats comming out of coil plce near ground. Now take the - side coil and short it to chassis of car. this should charge the coil then when you pill the wire off the coil should FIRE/snap cause it near ground. If you have this then the coil part works and your proplem is a triggering sytem. remember on a Matchbox B is positive C goes to minus side of Coil. Maybe try another dizzy.(make sure you put to TDC so you know if your on #1 plug wire and counter clockwise fire order. In the HOW TO section on this site it show different way to hook up different dizzys http://community.ratsun.net/topic/17444-electronic-ignitions-for-l-motors-4-cyl/ Quote Link to comment
