mikecaleb Posted March 21, 2020 Report Share Posted March 21, 2020 Ive got a z22 weber 32/26 swapped in a 86 nissan hardbody. It turns over pretty slow and will try to run for a split second. Im thinking i may have some ground issues. Does anyone know the grounding locations? Currently there is one ran from the battery to intake, motor to frame, frame to chassis. 1 Quote Link to comment
datzenmike Posted March 21, 2020 Report Share Posted March 21, 2020 Are you saying the starter turns the engine over slowly???? First clean your battery terminals and cable clamp ends, Check the ground on the intake is clean and tight. Check the positive cable on the starter is clean and tight. Make sure the battery is fully charged. Borrow a charger for the night and try again in the morning... any better? No? Us jumper cables to use a second known good battery in another vehicle. If this fixes the problem maybe your battery is just old. 1 Quote Link to comment
mikecaleb Posted March 21, 2020 Author Report Share Posted March 21, 2020 Yes it turns over slowly. And i will check and try that tomorrow. 1 Quote Link to comment
datzenmike Posted March 21, 2020 Report Share Posted March 21, 2020 If everything clean and tight and jumping from a good battery fails to speed it up this leaves the starter. But don't go out buying a starter or new battery till confirmed. It gets expensive throwing parts at a vehicle. A new battery won't fix a bad starter. 1 Quote Link to comment
mikecaleb Posted March 21, 2020 Author Report Share Posted March 21, 2020 (edited) I never realized it till earlier while doing some research but the z22 is supposed to have a clamp on distributor cap and a different style rotor. I have the later style on there as of right now. Is this going to cause issues? Edited March 21, 2020 by mikecaleb 1 Quote Link to comment
datzenmike Posted March 21, 2020 Report Share Posted March 21, 2020 The 8 plug distributor cap has screws to hold it on. Spark is not going to alter how fast the starter turns the engine. 1 Quote Link to comment
mikecaleb Posted March 21, 2020 Author Report Share Posted March 21, 2020 (edited) I know that. It had caught my attention earlier and just figured id ask. I was out looking at the truck earlier and there is an obvious ground that i somehow left out/overlooked. The battery is not being grounded to the body. It has a battery to motor, motor to frame and the little one on the firewall. The front clip is also grounded to the frame with a little strap. I got a little wire running from the distributor adjusting bolt to the timing cover too just in case Edited March 21, 2020 by mikecaleb 1 Quote Link to comment
banzai510(hainz) Posted March 22, 2020 Report Share Posted March 22, 2020 If you feel safe about it charge it up with another car and see if it rotates faster i seen cracked clamps or corrosion cause a low torq situation 1 Quote Link to comment
mikecaleb Posted March 22, 2020 Author Report Share Posted March 22, 2020 I'll test the voltage at the starter before and after just to see if theres a difference. Maybe thats my problem. 1 Quote Link to comment
banzai510(hainz) Posted March 22, 2020 Report Share Posted March 22, 2020 What you mean test the voltage? i think that would be hard to check unless there is a load bad corrosion one can put the meter on volts,then put one lead on the center post and one lead on the cable clamp. Put key to ON if you measure like 1 or 2 volts then that’s the problem if it’s still 0volts then the connection is good as there no voltage drop 1 Quote Link to comment
mikecaleb Posted March 22, 2020 Author Report Share Posted March 22, 2020 I was thinking that if i took the ign wire off the starter and measured it there with the key in start with the other probe grounded of course. 1 Quote Link to comment
datzenmike Posted March 22, 2020 Report Share Posted March 22, 2020 Measuring voltage does nothing. You could have 6 hearing aid batteries that read 12 v but it wouldn't turn the starter. Jump start from another vehicle. This eliminates your battery, charged or not. Turns slow still.... Ground cable on intake is loose or corroded Positive cable on starter is loose or corroded Starter is bad. Starter bolts are loose. Turns faster.... Your battery is not taking a charge Your charging system is at fault Your battery is bad. While the frame and the body need to be grounded the starter is grounded through the transmission to the engine to the head to the intake and through the negative battery cable to the negative battery post. Body ground does not affect this. 1 Quote Link to comment
mikecaleb Posted March 22, 2020 Author Report Share Posted March 22, 2020 Im aware of that also. Just throwing it out there. That ground is for the lights and whatnot in the front This aint the stock wiring harness. It's a painless performance universal kit. Everything works as it should so far besides for the slow turn over issue. 1 Quote Link to comment
datzenmike Posted March 22, 2020 Report Share Posted March 22, 2020 Painless?? Nice to find that out. 1 Quote Link to comment
banzai510(hainz) Posted March 22, 2020 Report Share Posted March 22, 2020 Ok I don’t think this would be the Painless wire harness but this is good to know for later issues . however the the starter turning over as you say it’s weak. The selinoid must be working as you say the starter is turning over.if the selinoid wire has a weak voltage the selinoid would most likely go click click click. but if you MUST you can pull the starter wire on selinoid and just put a wire from plus side battery to the selinoid tab and it will turn over bypassing the key. maybe click the battery at the starter post in case a crack cable or post the ground cable should be on the head or some times I seen on the starter bolt.That should be good enough.the other small grounds would not pertain as most likely they would melt if it was looking for a ground how old battery? replace batt cables replace battery replace or check starter 1 Quote Link to comment
datzenmike Posted March 22, 2020 Report Share Posted March 22, 2020 Z series has the intake on the battery side. There's a bolt near the thermostat on the intake for the ground cable. 1 Quote Link to comment
mikecaleb Posted March 22, 2020 Author Report Share Posted March 22, 2020 Yes it does the clicking after a few turns. The cables and starter are still new. But I have had the battery for a few years. Just a cheap walmart battery. 1 Quote Link to comment
datzenmike Posted March 22, 2020 Report Share Posted March 22, 2020 Clicking could still be a low battery. Jumper from another vehicle. 1 Quote Link to comment
banzai510(hainz) Posted March 22, 2020 Report Share Posted March 22, 2020 (edited) Well try putting a wire from + side battery to the selinoid tab and it should turn over what I do is put a female connector ok a wire and hook it up to the selinoid.then use the other end on the + side battery and it will turn over.if still clicking maybe selinoid contacts are weak. I’m only guessing now Edited March 28, 2020 by banzai510(hainz) 1 Quote Link to comment
