Shorted out the lead for the fuel solenoid.
« on: April 18, 2010, 10:54:31 am »
Bad news: Shorted out the lead for the fuel shutoff on the pump...

Good news: the solenoid still clicks when 12v is applied to it.

Had the key on with music playing while I was minorly tweaking the fuel screw a touch... Wrench touched the soenoid.. crap. Checked the fuses, yet all them are fine. What gives power to the solenoid? I mean if worst comes to worst, I;ll just tap in to the radio key-on source.

Man it billows like a cummins with just half a turn in. Don't worry though it was merely for a fun ride around the block.. not keeping it. ;) untill I get the intake and exhaust setup. :)

That solenoid isn't fused, rather lame.

Did you fry the wire or is it still lookin' good? I did that a few years ago, I had a splice in the wire and it was touching ground 'cause I'd forgotten to tape it. So I got in let the GP's glow and cranked it up :(, it didn't start since all the juice was going straight to ground.
The wire was smoking and stuff, kinda melted some other wires it was touching but they weren't toooooo bad.

If all you did was spark it I'd say it's fine, that's not enough time to melt stuff........it's probably hard on the ignition switch though with all those amps running through it.
'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

Yup.... no fuse on that wire... so chances are it's let go somewhere upstream. IIRC it's run off the glow plug relay on a lot of chassis.

The good news is that it's just a "power when the key is on or start" line, so pretty easy to run another line from something.

it sparked it was a momentary touch of the wrench. Line shows no voltage. ;(

Pretty sure it's powered from the GP relay.

Sadly it's not that easy to just wire up to the stereo wire because you won't have power while cranking, and well you know.

swap GP relays from one of the other cars in the fleet and see what happens.

Ok, come by the shop and buy some fuel hose to fix your leak and I'll give you a relay. How's that sound?

You may have burnt out part of the relay. Everytime I've shorted the stop solenoid out I was lucky/quick enough to not cause any serious problems.

It's not my fault you posted this today :P

You know though, I only have fast GP relays. So I don't think I could be of any help anyways.

On my diesel conversion, I ran a wire tapped from the ignition switch that had power while cranking and on.   no switch needed, and nothing really gets modified other than adding one wire.   ;D

Yup, there should be lots of circuits with that criterion to tap into.  The ones to avoid are the ones driven off the load-reduction relay, since they're specifically un-powered when the starter is engaged to free up extra amps.

would adding an inline fuse be a bad idea? If not what would you put in there Vince?
