I have probably read all previous posts regarding this issue. My '69 Chevelle SS396 4 speed is still having problems getting the starter to turn over when the car has been driven for 20 minutes or so. I have a brand new Optima battery, trunk mounted with 2ga.wire & all grounds & connections are fine. Remote solenoid, new gear reduction starter w/heat shield, new HEI module, new alternator, timing was slightly advanced, that has been corrected. I was wondering what size wire should be running from the remote solenoid to the starter. That is the only thing left I can think to change. Sorry about the long post, any help is greatly appreciated.

Have you tried jumping the start terminal back to the battery when the car has a problem? This is the terminal where you tied the purple wire from the ignition switch. Hang a wire on that and cap off the other end. When the car acts up, take the capped off end, uncap it, and touch battery (+).

First thought is that 2 gauge wire running from the trunk to the starter is way to small to crank a 396. I'd think 1/0 or 2/0 wire is more likely to work.

Describe what it does. Does it crank slowly or not engage at all? Any other info?

It cranks very slowly. The wire that connects to the starter from the remote solenoid is 4ga. Should that also be 1/0 wire? Thanks.

Yes, Personally, I'd run 1/0 for all the wiring from the battery to the starter and also for all the ground wires. This is because it's a trunk mount and has extra wire length. 4 guage is way too small and 2 guage may work but then again it may not.

Second the 1/0 wire. You need all the current carrying capacity possible.

Jack, with the positive and negative cable lengths measured I'd say it's about a 25 foot run. According to that chart, 2/0 is good for 140A to 180A which is right about what the starter probably draws. But, if you use 2 guage all the time then it obviously does work. I just figure the 1/0 won't cost that much more and it definately won't have a problem. At any rate, 4 gauge is way too small.

Sorry for the slow response. I will replace all wiring with 1/0, I can get it for nothing from the electrician I work with. I am getting quite disheartened with the whole muscle car thing lately, namely the $$$$$$$$$ that has been adding up, if this does not solve the problem I might be inclined to put this precious thing on the market. Thanks for the info.
