You've got to have amps to do work. DC motors like to have a good power supply that can keep voltage up when the motor is loaded.

Well, I am still an idiot but as I lay awake last night it dawned on me that I was using my tabletop power source to try to raise the window glass. It works well to test the motor and regulator on my workbench but does not have enough power with a load on the motor.

I rolled the battery over to the passenger door today and hooked it up (through the relays of course) and the window goes up and down link a champ.

I'll sleep much better tonight.

I finish up my modification posts after I assemble all the photos I took.

Also, I finally got the steering wheel painted today.

A couple of projects today.

I replaced the wallowing out brake adjustment eccentric in the rear drum and then finally was able to get that adjuster to lock down.

While I was under the car I figured I would recheck the front brakes. They both needed several clicks of tightening. Interesting. Probably now that the shoes have bedded and the high spots were worn down on the shoes, then needed some tightening up. It made a huge difference. The pedal feel is much better with less pedal distance. I can now lock up all four wheels if I try. So note for next time I replace shoes, recheck them after driving a bit, as they made needed a bit more tightening.

Also the parking brake will now hold car on a hill from rolling backwards.

Also another project I did was add an underdash light. There was an underdash light in a box of parts that came with the car. Not sure what it came off of, but it had a 6v bulb in it. So I swapped it with a 12v bulb and repaired the frayed socket wiring. I hooked it to the same side of the switch as the reading/map light, so it comes on with the map light. It should help light up the interior at night when needed.

Early in my career we had the king of the mechanical calculators, the Monroe-matic IQ which could also do multiplication and division! That would have been about 1970 or so.

The first pocket calculators were quite a shock. In that day, many offices still used mechanical adding machines that weighed 20 pounds or more.

Other items not often mentioned besides the huge amount of electricity needed is the cooling for the thousand or so vacuum tubes and the noise generated by hundreds of mechanical switches and telephone style rotary searching relays, both of which make a fair amount of noise and have their own problems. The first computer "bug" and the reason for the name that stuck around and is still used today was actually just that -- an insect few into one of the relay or switch mechanisms and jammed it causing the machine to make an error in a calculation.

I don't know about the others, but if Kevin (BigKev), Howard (HH56), John (JWL) or I had a computer that was -> older than us, we would need a private hydroelectric plant to provide the necessary electricity.

The shadow is black paint. The distributor must have been worked on in the past as it had a bad rebuild shop paint job.

No I have not yet done that… I suppose your right I hadn’t considered that as a factor yet.

I've got an old SE/30 and an Imagewriter; replaced the PRAM battery a few years back, still plays Oregon Trail....
