Fuse Block

[Project Comanche]

I recently installed a speedo cable and I am happy to say it is working well. In the process of gaining access and wiring the radio I lost power to the following areas:

 

Radio

Blower

Turn/ B/U

Inst lps

Cigarette lighter

 

Before everything was working fine

 

I have checked and fuse block has no power coming into those areas. All fuses are fine and in-tact.

 

I have checked connection behind fuse block and it seems to be fine.

 

I changed, loosened, shorted something when fidgeting with the dash, but what was it? Any help would be greatly appreciated.

Sounds like the connector to the back of the fuse block has worked loose.  Out on the firewall, remove the plastic dust covers and see if the bolt in the center of the two halves of the connector has backed off.  Wiggling the connectors may temporarily bring power back to the fuse block.  if so, you have found your problem.....

you may have to separate the connectors from the fuse block, because they are filled with the same black tar that is in the c101 connector.  the tar may be acting as an insulator on the inside between the connector blades and sockets....almost any solvent will clean it out......messy, messy

I wiggled the connectors... No change. I was afraid someone was going to say more tar. Just recently did c101 connector. It is just strange it changed when I was taking/putting back together the dash. I'll check that connection more in-depth. Another question... There are two bolts on the drivers side just in front of the kick panel, I thought those were for grounding wires? There are zero grounds on either of them.

 

What is this part to the left of the fuse block? Mine seems in bad shape.

Have a peek at the plug on the electrical portion of your ignition switch. Probably loose/burned.

Seems like a likely culprit, ignition has been acting strange recently. Electrical portion located in column?

On top of column just under the dash.

Be sure to post the problem and the fix when you fix it

Checked the plug... Did not change anything. I know there is just one wire or plug that has a bad connection... But where? Recently rained and I realized no wipers along with the above list. Any other suggestions for tracking down the cause? Could it be the ignition switch itself?

Yup, most likely.

Finally got some results today. Laid under the dash and checked every connection again. I didn't think I did anything and then went for a drive and the blower motor kicked on. Surprise. One of the connections must have needed that slight jiggle. Happy to have it fixed. Hopefully it is here to stay working
