izzo Posted June 29, 2009 Report Share Posted June 29, 2009 7 months ago when i picked up my truck, i thought something was wrong with the wiring. Battery would die every few days, got some good help figuring that out. Turns out it was a dead cell in the battery. Its almost acting like that again. First, it would just "Click" and nothing. I would head the started click once then do nothing. Ok, jump started it, thought maybe i left something on? I did have the stereo going for half hour. That must have been it, wrong.. I drove it around for a few hours and got a good charge back on it (keep in mind im 370 miles from home with no volt meter) It will start back up a few hours later no problem. I checked every possible switch inside the cab to make sure everything was off, or unplugged. Including the dome light, Cig lighter, stereo etc. & also made sure the batter terminals were tight so everythings good there too. The next day when trying to start, it does turn over. When a battery is low it will make a click sound inside the cab somewhere. When you press the starter switch, it would turn the engine a quarter turn (so i think that means 1 full turn of the starter?) after every 1 turn of the starter i could hear it click inside the cab, then it would turn again, then i heard the click again etc etc over and over luckily it started. It died one more time after that. So, got another jump and everything seems to be fine again. I drove 6 hours straight and stopped off at Slayers country kitchen in portland, was there for an hour, come out and it happened again. Every time i hit the starter button i just heard the starter click and nothing happened. I kept hitting the button over and over, and finally it just kicked over and started up. anyone have any thoughts on whats going on with this? Just got a voltmeter in the mail thanks to mosier, installing this week Some thoughts i had, i noticed my turn signals didnt work so thought that maybe the hazard switch was not properly disengaged so it killed it Maybe the starter is going bad? maybe i should replace the wires for the battery?? :confused: Quote Link to comment
yello620 Posted June 29, 2009 Report Share Posted June 29, 2009 I think that the click that you are hearing is the starter solenoid. Right on the other side of the passenger floorboard. Your starter is clicking. IE-starter solenoid engage the drive gear to the flywheel. But your starter is dying and the motor is not spinning. Quote Link to comment
izzo Posted June 29, 2009 Author Report Share Posted June 29, 2009 Thank you Jason! Time to hit up the classifieds... Just strange to me it didnt start this until the trip. Have to see if anyone has a starter I guess. Thanks again man Quote Link to comment
stilltwisted Posted June 29, 2009 Report Share Posted June 29, 2009 check the batt cable for corrosion ,,make sure the sillinoid is not cracked,,i had that happen on another car,, Quote Link to comment
izzo Posted June 29, 2009 Author Report Share Posted June 29, 2009 (edited) havent checked the syl, cable looks good. negative cable looks a little old n what not ill try and get pics tomorrow, may have to make a trip to freaky510's for some parts :D btw, theres two diff clicking noises. i know the one from the starter, but theres another from in the cab near the fuse box. maybe its something they put in the 720s. Datsun mike probly knows. ill try and look it up in the book tomorrow Edited June 29, 2009 by h2theizzo Quote Link to comment
datzenmike Posted June 29, 2009 Report Share Posted June 29, 2009 The '80 720 is an odd ball. Besides having the last year L20B and all the differences that brings, it also has a slightly different wiring system in the cab from all other year 720s. The fuse box is different with fewer fuses than other years. There are a lot of relays in the 720 as well. I'll take a look when I get home but the click may just be an ign. 'on' relay.

datzenmike Posted June 30, 2009 Report Share Posted June 30, 2009 Clean the battery posts and the clamps that hold the cables. The fact that a jump fires it up precludes the starter being bad. Something is draining the battery or it's bad. Disconnect the pos terminal and connect a test light between the cable and the post. If on it could mean there is a draw somewhere. If you have a clock it will be on. Now start removing fuses, when the light gos out you have found the circuit with the draw. This will narrow it down. Try also pulling the plug out of the alternator too. A bad diode may allow a discharge when off. Quote Link to comment
izzo Posted June 30, 2009 Author Report Share Posted June 30, 2009 theres no plug on my alternator not sure what its out of but the plug is just sitting there, two wires are connected to the alternator I installed a voltmeter into the cab today, ill get it hooked up tomorrow. tested it and it works ill update this in a minute gonna hunt the camera down and take a picture Quote Link to comment
izzo Posted June 30, 2009 Author Report Share Posted June 30, 2009 lol, guess there is a plug there but its never been plugged in, never saw the spot for it before these pictures. i figured someone put a different alt in there. the volt meter was just above 12 when i tested it.
