Is it ok to Bypass Ignition-Relay-Starter Wire
« on: October 08, 2010, 04:17:08 PM »
I've read some threads and I am having a similar issue.

The relay was bypassed from the Ignition to Starter Wire, it had a 30amp inline fuse that eventually started smoking and caught fire.

People have said that you can just hotwire the Starter Wire to the Ignition without issue. I tried the hotwire method and it works.

I just want to get a solid answer on if it is ok to hotwire them and be safe to drive around without a fuse or running to the clutch pedal switch.

I am guessing the only reason why the Fuse caught on fire/melted was because it was seeing too much power on the starter wire side.

Thanks in advance guys.

Hint - your starter pulls just a wee bit more than 30 amps....
That will definitely sizzle your spit   :bacon:

It is 40 amps correct? lol

Problem being, you cant get an inline fuse bigger than a 30amp. (atleast at any of my local autoparts stores)

Just got ahold of my friend that is pretty savvy with LS1's and their harness, he said its ok for me to hotwire it.

*fingers crossed I don't have anymore fires* lmao

You aren't looking at the amp draw for your STARTER itself - there is no/should be no fuse in between the battery and starter (the BIG wire).  If there is, get rid of it.  What you are seeing a fuse for is the starter SOLENOID.


unless you own a turbo ls9 rx7 you do not know what the fuck you are talking about.

Your post kinda confused me.

The wire I am talking about is the purple wire, the one that runs thru the harness and connects to the smaller bolt on the starter.

yeah, what speedfab means is the wire you are talking about, the purple one, goes to the starter solenoid.


and no, i dont think the ignition switch itself is capable of handling that load.  a relay should be used.

Well the car runs with the starter solenoid wire connected to the Ignition wire without issue so far, its only seeing power in the Key Start Position. (this is how that 30amp inline fuse was connected for 800-900 miles on the car)

I am going to buy a fire extinguisher just in case, I'll report back with a few miles on the car to see how it goes.

Car ran fine, no problems at all and the wires didn't feel hot.
