Firewall-Mounted Solenoid
I should know this by now, but can anyone tell me how to wire up a firewall mounted solenoid and which one to buy?

I Googled it for you cause it's been a while since I did mine. Definitely a worthwhile addition if you run headers.

Re: Firewall-Mounted Solenoid
I used to run on on both my other trucks, but with my Hedman Shorties I haven't had to do it on this one.
Google wiring a Ford solenoid on a Chevy.

Re: Firewall-Mounted Solenoid
I have the Dynomax 3/4 length Chevelle headers still in the box. I wonder how they'll do.

Re: Firewall-Mounted Solenoid
I rigged a Ford-style solenoid on my '71 Jimmy w/ Hedman headers. I mounted it on the passenger side inner fender.

Re: Firewall-Mounted Solenoid
Stop calling them FORD solenoids!!!!! GM used them too you know! (Only on some campers. They are all the same part number) J/K! HAHA

Re: Firewall-Mounted Solenoid
You know this topic comes up every now and then. I'm 54 and have heard of this "fix" from way back when but I cannot for the life of me understand how it can help a heat soak situation. You still have wires going down to the starter solenoid to activate the starter. Those wires still get hot and lose amperage same as before.
What I learned to cure the problem "way back when" was to take the starter to a local starter/alternator shop and have then beef up the starter using Delco parts, of course. A stock small block starter has 2 fields and 2 shunts adequate when new but after some time will weaken. Our starter guy put in 2 more fields doubling the starting power of the starter and solved ALL hot start problems forever. It cured the problem on every one we did. It did cost a little bit more than this ferd solenoid fix but no wiring had to be added or modified. The only possible benefit I can see with this fender mounted solenoid is the shorter distance for the S wire to travel from a solid 12volt source so maybe less amperage drop before it gets to the starter. Another idea is to pick up a mini starter from the salvage yard. I think they started using them somewhere in the mid 90's. I am told they are rock solid with roller bearings and planetary gear set they are stout and last forever. Anyone used these yet? It would take less amperage to turn this one over.

Re: Firewall-Mounted Solenoid
I don't know why the remote solenoid works, but it does. Solved a hot start problem I was having because of my headers. I am interested in a starter upgrade at some point though.

Re: Firewall-Mounted Solenoid
I'm just getting back into this after several years off, but I remember some part that would physically sieze up when it got hot. Or maybe it was the contacts would separate when hot? I never thought amperage drop was the issue?

Re: Firewall-Mounted Solenoid
It's those damn cheapo solenoids they use now....can't take the heat. Boog's fix sounds like the bomb to me, but I have tried the F Solenoid and it does work. By using it the wire gets routed away from the headers or manifolds much better than the stock config.
I do like the idea of beefing up the starter. Yes the mini's work great...had one on the Elky and never had a problem.
