Re: starter solenoid

I'd suggest replacing the starter, that's the problem. Had the same problem in my car last year with a starter that had been fine for many many years. Might look into one of the small late model permanent magnet starters, probably won't be as close to the headers. Worked out well for me.

Re: starter solenoid

I've never had to do it (YET) because I found out long long ago that headers are not worth all the trouble that they cause for the little horse power gain on a street driven car but here is one way that somebody posted.

Re: starter solenoid

IF I was going to install the Ford type solenoid I think I would do it like this.

Re: starter solenoid

I had starting issues with my 70 - 468. The old, GM starter was having a tought time doing its job. I bought a NEW Delco Starter with the one piece housing, 70 style ( short HI/Perf Solinoid) and the top thru bolt was designed (long enough)to attach the 70 starter brace.
The New Delco spins the 468 on a VERY HOT day & HOT engine, Like the plugs are out.
Good cables & wiring & starter..... You will be good to go.
When you are in your 70s ,,, You learn. " Good parts aint cheap & Cheap parts aint good "

P.S. this was 5-6 years and 34.000 miles ago. I had headers in the 70s / 80s, For a race car, Excellent. For a street machine, A Hellava lot of work & Pain for the end result. Do what is best for you.

X2 this is correct. Starters that don't work when the engine is hot are bad. It's also likely that using a remote solenoid won't make any difference. Replace the starter with a high quality replacement like a high torque Power Master.

Re: starter solenoid

If you decide to go with the ford solenoid get the start-em up kit from mad industries comes with what you need and Mark knows his stuff. Put mine on in 1989 when engine was rebuilt and tight probably don't need it now but has been great and you can hide it if you want.

With the battery in the trunk and saying you are using 1awg welding cable, do you have a positive cable and a negative 1awg wire going between the battery and the engine ?. If you are running just a 1awg from the battery positive up to the starter and using short connections from the battery negative to the back of the car, do you have another connection between the front of the car and the engine block ?. The power has to make a loop and if there is a restriction in either the positive or negative path, the starter might not be getting what it needs.

Another thing to look at is with a rear mounted battery, where is the voltage sense wire on the alternator connected at ?. If the voltage sense wire is up front, then due to the voltage drops on the cabling back to the battery, you may have 14 volts up front but in back have less to where the battery might not be getting fully charged.

Another thing to look at is the connections on things like the 1awg cable. Sometimes crimped on connections are fine and last a long time but maybe solder the lugs onto the wire.

The powermaster 9100 installation manual also states that the starter is not designed for high compression motors. They also suggest using a 1awg when the main cable is 7' long. If it's closer to 10' then they suggest using a 1/0 cable.

Also, has it always been this way or has the issue slowly been become worse and worse ?.

Maybe the battery is weak ?.

Yep, that would work fine too.
There is no "I" terminal, it should be labeled "R" on a GM starter but I guess it doesn't matter since there is no wire on that terminal (if no points).

Actually, I personally believe that although it does work, installing the second solenoid is really fixing the symptom rather than fixing the cause which is usually not enough power to the "S" terminal under load caused by poor connections but it is a lot easier than fixing the cause.

IF the battery has be re-located, refer to post #10

That's been pretty much the totality of my experience with this "heat soak" stuff. That and properly sized wiring with soldered, heat shrunk connections. Takes lots of time but worth it.
