Starter Relay, Stancore?
Anyone know of a stancore style replacement I can do for the starter relay?
Or can I just use a the GPR stancore?
I don't know nothing about these style of electronics. I'm afraid that the GPR will have to big of windings and burn out the starter?

The relay uses a wee amount of current across the small terminals, and connects ("contacts"; IIRC, Stancor calls it a "contactor") BIG current across the big terminals. It doesn't _draw_ any current across the big terminals, so it can't harm the starter (or whatever it's connected to) unless it's providing too _little_ current (or there's too much voltage drop). A bigeffin' relay like the Stancor is designed exactly to avoid that.
Only thing is, the "coil" (low current) circuit of the starter relay completes its circuit through its mounting on the fender (which is why they'd fail when old Mavericks/Pintos would rust so badly....), whereas the GPR completes the circuit through the second little terminal. So to use a Stancor-style relay, you'd have to run a wire from that second small terminal to a ring terminal and put it behind one of the mounting bolts. This is why you could use such a relay for the starter relay, but vice-versa (using a starter relay for a GPR) won't work.

So, your saying, Just buy the stancore, mount it on the wall and ground one of the terminals?
But both terminals are used on the starter relay are they not?
I can't recall the wiring at the moment.

Ground one of the small terminals. The OEM and replacement starter relay has only one small terminal. Power comes to it from the ignition key switch, and the coil circuit completes through the mounting base. To mimic that with a relay like the Stancor, with two small terminals, indeed you connect the ignition switch wire to one terminal and ground the other.

I'm thinking I should put my old GPR on, and switch the stancore to the wall to test this.
Lots of people have starter relays go out, figure should be some sorta perm solution like the stancore.

Hmm, I'm surprised. The starter relay typically runs for just a few seconds each time its used. Maybe 20 seconds on a cold-effin' morning. The GPR runs a minimum of, what, 30 seconds, up to two minutes, depending on conditions. I always figured that's why it calls for a more heavy-duty solution. Depends on circumstances, of course; lots of shorter trips means more hits on both relays.

How often does a starter relay fail? Not often. And when it does, you can jump it easily and get your rig running. Don't make something simple so complicated... if yours is bad buy a new $10-15 starter relay and replace it.

yep, i changed my starter relay just out of preventative maintainence and it only costs like $15 at advanced... the GPR actually has never been changed on my truck either and it's got 315k miles now... I better get a stancor already...

Travis, you said yours doesn't even work last I talked to you about it. haha.
Chase, I'm just looking for another excuse to put a second stancore on my truck.
People already get a ****** when they see the one for my GPR and they start asking questions.

i need to do the stancore gpr on my truck my cheep o-riles relays never last more than a month, before i have to start tapping them in the morning to start the truck, they keep replacing them for free but its getting very old probably been threw 12 of them in the last 2 years

Yea, you probably using a starter relay, because they gave you the wrong one.
Lots of threads on here about it, but i dont think i have a link saved for the relay.
Worth every penny.
Best part about it is, the auto store ones are 80 bucks, the stancore is only 55
