On this post I am going to concentrate on what I did about my non-functioning gauges. They were all fried with the ammeter blowout before I bought it and then the post new harness failure of the dash Voltage limiter. I had a spare cluster, but as you will see, it's also doa...
First the van
The Door decal remains(Palomar Mountain Observatory)
And it's original owners.
So The Limiter fried, and I made my own for $4.00 in parts from Radioshack
Installed on the back of the cluster. Note the 18Ga. brass plate for a heatsink. I also cut off the 12 volt side of the dash bus at the gas gauge.
I got it all wired up, verified that the original temp gauge was shot, Verified the boneyard unit worked, and promptly destroyed it by pulling too hard on the wire...
Back to the drawingboard. Went to Carquest and bought a cheap electric temp gauge kit. Decided to add a volt meter from an airplane I had lying around. I cut the dash out where it was damaged by the PO. Idea here is this is temporary, Going to either have the original cluster rebuilt, or get all new quality gauges, either way, where I cut the grill will eventually be filled with a stereo. So... Here goes my first A100 hack...
Dremels are great!
Test fitting and cuts done with a hole saw and a jewelers saw in 18Gauge copper.
Wiring harness
And here it is working. Added a 12vdc powerport on the bottom and also terminated out a setup for dual USB from the 5vdc circuit that I will install a little later.
What did I learn? I heat up to 210 on steep climbs but tends to run at 190.
