Howdy Gents:

I'm planning out my electrical for a remote battery (trunk mounted) whereby a starter solenoid is also mounted in the truck thus preventing an always live" high current cable up to the firewall.

My question is that when this is done the "starter" and "battery" terminals are "jumpered" because you now have a remote solenoid. I believe the LSx starters are permanent magnet type and I've heard of problems (not necessarily with LSx engines) with the starter exhibiting "run-on" caused by the starters turning into generators for a couple of seconds after the key is disengaged.

Does anyone have experience with "jumpering" LSx starters? Is this a problem?

Thanks for the help!

You cannot jumper that starter. You have to add a relay to trigger the solenoid on the starter. You have to tie the relay into the trunk mounted solenoid so they both work together. It will act like a generator.

Ahhh... that's what I feared! What about a diode between the terminals?

Thx!

ive done exactly this for three years with absolutely no issues. three different engines, same setup, no problems

... With a diode or without?

Thx!

I have heard of this issue here recently as well, I did my swap in 2008 and I have a LS2 & T56 out of a 2006 GTO, I also have my starter jumpered with a heavy gauge wire and am using a Ford solenoid to activate my starter and I have not noticed any unusual run on or starting issues.

... That's exactly the combo I have. Thanks for the info!

NO DIODE. just jump the big and small terminals on the starter, then the battery wire from the ford starter solenoid.

I tried it on the 5.3 in my '84 LTD with the Ford starter relay, and the starter would stay engaged foe a split second after starting, so I did away with the Ford solenoid and all was well. I tried several starters thinking I had a bad one, they all did it when wired that way. Just my experience with them.

Yes, it WILL soon or later ruin the starter.

What about something like this? It's a 40A 600v blocking diode and costs $7.00 shipped to your door.
