For non-indicating or faulty gauges, the oldskool method was to ground the sender end. That would normally send gauges hi (FSD) though in rare instances GND could mean a low/zero value/deflection.
HOWEVER, with modern cars with more sophisticated electronics, that method could damage the electronics. Although that started circa 1980, it didn't effect most vehicles until much later. Some pro wrote recently that "ground-short testing" ceased in the 1990s.

But in your case, I reckon disconnecting the sender would have released the gauge from FSD.

Pity I've been distracted with aux batteries etc.....

I actually already knew this stuff, but it'll be good for the newbz who actually know how to RTFM (or, I guess FAQs, in this case) and

and may need this. Thanks!

If I unplug the gauge, they both stay at full. I haven't had a chance to actually drop the tank and unplug it from there yet. Probably this Saturday (your Sunday, I believe...?) Worst case scenario, I'll have to drop ~$250 on a new fuel pump/sender module. Either way, the tank comes down...

Wind was blowing horribly (65 MPH gusts), so I didn't get to drop the tank to check anything out...

Oh, well. I got my SAT test done anyway.

Also, I installed my car alarm. I was at my friend's house until 2AM this morning. My mom

a brick, but I got it all done. My ran into one small problem, though. I had to unplug the siren because something kept setting it off. I'm wondering if the shock sensor is set to too high of a sensitivity... I'm going to start ripping wires after church, which is where I'm posting from now, but that's another story...

It turns out I had the constant 12VDC and GND lines to the alarm switched...

I'm going to have to use this diagram to be able to use the siren though. I only get 0.02VDC out when the siren is supposed to go off... I think I

it up...

I've determined that I'm going to just cut the hole for the monitor mount and then fiberglass it up to hide the holes/gaps. Now I just need paint to match the interior. IMO, it's the best/easiest way to go for me because I'm tired of not having my XM in my car.
(My CD player thinks all of my master CDs are yummy and spits all my copies out at me with random read error BS, PLUS this God-forsaken town doesn't have any decent alt-rock or hip-hop stations that mix things up. (As if BPM and Hits 1/20 on 20 are any better...). Think I'll try cleaning the lens on the CD player...)

Three more weeks of school! Then, I get a week off and it's off to college prep classes (AGAIN!) By the time college actually rolls around, I'm going to be SO sick of school... (At least in college you can party somewhat legally...

)

When you do this, dont forget to make it so the screen can be taken out. That way if it breaks you can simply swap it out with a new one.

Well, i had a "date" tonight, but her mom decided at the last possible

second to tell her she couldn't go, so now I am working out my frustrations on the screen bezel.

Pix to follow...

This is what it looks like from the front:

I need to fill this in with some fiberglass jelly tomorrow...

This horrible photo is supposed to show another gap, but I kinda got too close and it glared. I'll try to retake it tomorrow before I fill in the gaps and level everything out.

Any comments?

**freeflashstuff** · 05-09-2010, 12:59 AM

I retook the photo tonight. I'm going to sleep now. I'll post pix of the gaps getting filled in tomorrow if I actually get around to doing it...

Waiting for more pics.

Of course you are... I'm at church right now. We haven't started yet, but after this I'm probably going to take my mom out for lunch and then when I get back, I'll try to get some work done on that. Then I'll have some pix for you, Tidder.
