Hot Start Solution fo my Truck

[leddzepp]

A thermal wrap around the solenoid/starter eliminated my hot start issues with an OEM starter. I've never had that problem with a mini starter.

In both cases that is because keeping the starter temp down, or using a gear reduction with less contact surface, both serve to reduce the voltage needed to fire off the solenoid so will "crutch" a marginal solenoid wire circuit.

Your grandpa's purple solenoid wire in his '63 Biscayne Four Door always worked because no one monkeyed with it, cut it, or otherwise compromised it. Otherwise GM would have had a rash of warranty work every time it got hot in the South.

I'm talking about stock setups; I'm sure it's possible to cook a starter enough with headers that some insulation is required.

I don't think the starter-to-block ground is a common problem, as once you managed to get the solenoid to fire you'd still have a marginal starter ground so it'd crank slowly best case.

I don't think that is and acccurate statement.

Look inside a GM starter. It is not physically possible to bypass the solenoid in any way, shape or form, because it uses electromagnetism from the current drawn to operate the pull in winding, which pulls in a plunger, that gets held in place by the hold-in winding. That plunger is attached to an arm, which engages the drive gear into mesh.

I just tore down a reman two weeks ago, they haven't changed yet.

Lets put this in easy to understand terms.


All the solenoid does is move the small purple GM starter wire to the new solenoid and uses a bigger heavy duty cable to feed the GM starter and jumper the small "S" terminal on the GM starter to engage it.
You are not bypassing anything.
This is how all newer vehicles are wired now form the factory except they use relays instead of the solenoids.
I bet you could use a 50 amp relay like for a fan motor and do the same thing.
When you think about it it's just like the relay kits for your head lights. Your taking the load off the main electrical system and using relays are in this case a solenoid.
Both are serving the same purpose as a electrical ON/OFF switch for the circuit.

Well I certainly appreciate all of the knowledge. I guess I never put that much thought into it. I fixed my heat soak problem with a remote soliniod ages ago and moved on to the next project.

X2. I fixed the problem and moved on. There are many ways to solve an issue, as long as the end results are the same it's a success.

I agree. Everyone has things they're passionate about, and I think it's great. It gives me the opportunity to learn about something, every time someone goes off on one of their passionate subjects.
