Hey Joe,

I knew I would not sleep If I didnot go and try your suggestion, and sorry to say, it made no difference. I grounded the relays out against the steering column and then tried other area's using a jumper wire and still did the same thing.

The volt guage goes to zero and I lose all power to the fuse panel when I take the shifter cable off the shifter. As I have mentioned earlier, the signal indicators come on bright when I take the shift cable off the shifter.

NO BEER FOR YOU until this one is solved!! LOL

Do you still have the jumpers on the dash to the steering column?  That steering column bracket could make a difference.

 Well... from what I'm reading, the shifter "cable" is the only ground path
that's really working. Needless to say, that's not right.

 Do you have continuity between the top most metal of the shifter assembly
and the vehicle's ground (chassis)?  your pics show a wire drivers side forward
using that assembly as ground.

 Are the engine to chassis ground straps present?  is there continuity?

I was at work today and it was bugging me and I had the same thought. Is the engine ground hooked up? and the answer is NO!! it's not. I am going to hook it up and see what that does. I am quite sure that will solve the problem. I will let you know what happens.

Ok here we go, BINGO!! engine ground was off. The shifter was acting like the main ground for the car, I am sooooo close to having all the problems fixed, just one more thing to fix and I am done on all the electrical stuff.

When I have the interior light on and I push the wiper button for fluid, the dome light goes out? The wipers work fine, I do not have the wiper motor bolted to the car, I just plugged it in and ran a ground wire to the firewall to test it. Any Ideas

Have you installed the steering column bracket?  That might help.

Joe, good call on the engine ground!

No I havent installed that yet, I am waiting till tomorrow to do that. Thanks so much for your help, you and Joe are real assests to this form.

I kinda lied about having one thing left, It's not a big concern but I noticed the clock was not working, How can I test it and is it typical for them not to work?

 Grounding the Dash properly is a very common problem.

 Grounds are one half of the circuit, in other words... if the grounds
don't work - nothing electrical functions.

 The steering column bracket IS a big part of the ground path for anything
that's in the dash (it's anchor points/bolts left and right also). That's why ta78w72
is mentioning it. It may not have responded before because the the other (engine)
grounds weren't functional.

 Glad to hear it's all coming together, I hate to hear that a free beer supply is in danger...
<grin>

 I'd mount the thing to test it, I think I found that jumpers didn't help one time that I
tried the same thing.

 The clocks can be repaired/replaced, fortunately that's a well beaten path.

 As far as help, our thanks are picturing yet another TA owner smiling as they fire-up and
roll into the flow of traffic. You are part of a special community here...

Well Joe, The Beer is never in danger ( I had to use a scare tactic you know), If ever either of you guys get out this way, I promise a hell of a good time. I will put the steering column up tomorow and let you know what happens. I will also mount the wiper motor to make sure.

I think I will just leave the clock alone, I am not concerned about it. Someday I will look into getting it fixed

 Hell, you guys have given such good advice, if you told me is was a wise idea to dance a jig before hooking up the battery, I would consider that also LOL

Now that I have put the column back and bolted everything tight and plugged the signal switch in and bolted the wiper motor onto the car and plugged that in, the wiper switch still does the same thing.

After closes examination, I have noticed that I can just barely touch the switch and not even set off the washer and the dome light goes out. Could the switch be faulty?

Any idea's how to test the switch, why would the wiper switch affect the dome light, is the question.

The door jamb switch on the drivers door is broken, could that have something to do with it? I am getting a new one today hopefully from the dealer.

 The dome light comes on with full rotation of the headlight/parking light
switch (inst panel dimmer), in addition to opening the door.

 Since the wiper switch AND the headlight switch are sitting in very close
proximity - with their wires lying just about next to each other, I'm thinking
maybe they might have a common ground...

 Lemme think about that a bit, (and look at the diagram).

Ok, you think about that and I will sit here, drink beer and wait patiently.

 Well the wiper switch does use a instrument panel
ground... the headlight/dome does not...

 Pulse wipers? or standard?

 Do the instrument panel lights work and change
intensity?

 The wipers work?

It is standard wipers,

The instrument panel lights work and change intensity.

The wipers work.

When I push for fluid the wiper motor clicks? it is still turning but the little cam under the plastic cover clicks up and down once.

The fluid motor on the bottle does not work, I put a jumper right to the battery and the little motor on the bottom of the bottle does nothing.

Out of curiosity, why is there a little motor on the bottom of the fluid bottle if the wiper motor has it built in?
