UPDATE ON VACUUM A/C: When I installed the little tiny vacuum pump, I ran the hot to the blower hot, and the neutral to the blower neutral. The speed of the blower is controlled by the resistors on the neutral leg, so as you turn the speed up and down, you also turn the little vacuum pump up and down. I was still losing vacuum when I stomped on the gas for a while. So I moved the ground to the fender, and I put the second soup can back in. So far so good. Ice cold AC is a good thing, you guys should try it.
NEW ALTERNATOR: I got a rebuilt 130A alternator and put it in the Road Ranger.
I upgraded to the 130 2-3 years ago when I added the second battery and a lot of the horns and lights and such, but the unit I received was a lemon. Instead of just sending it back, I worked out a couple bugs. Pulley was loose, the cover on the shaft on the back was missing so I made one, etc., etc. Well, I never got stuck on the road, but it acted up three or four times so I finally bit the bullet and put in a replacement. There was no core charge, so I’ve got the old one for parts.
DIGITAL CLOCK/VOLTS/TEMP: I have OEM radio that has a clock, but it’s very hard to see in the sunlight in the daytime. Also, considering the alternator problems and all my extra junk, I wanted a little separate voltmeter to just keep an eye on things. I’ve seen some aftermarket combination units, but they were all too big and they just looked like crap. Then I found this.
They’re only 1/2” high, a combination unit, but don’t have any cover or case. I got two green ones and one red one. You can easily set them to alternate between all three modes, or alternate between time and volts, or time and temperature, and they have an internal memory, so they turn off when you turn the ignition off, but don’t lose the time. BTW, it’s not engine temperature, it’s the temperature inside the cab. I put one of the green ones in the Road Ranger, in a low part of the command center.
Push/pull for traffic advisor bar on the shift, clock/volts on top of the brake controller, Radio Shack SSB CB. To the left, black cap is pepper spray, with a Chapstick and a nasal spray in their own sleeves (don’t get old). Besides the original drink holders, on the right, I added a cupholder for Lincoln‘s water, and a little prescription bottle for a couple pens and pencils and a comb.
In the pictures, the dead digits kind of show through, but that’s the camera, just looking at it with your eyes it’s jet black and only the numbers show. And of course, I immediately used it to check the new alternator. On vs battery
I made the little housing/holder from a piece of the frame of a fancy baby carriage that I bought at Goodwill for 10 or 15 bucks a couple years ago. The two holes on top are so I can access the tiny buttons that you use to program it I’ve used the stroller parts for all kinds of stuff, good quality materials. Goodwill is kind of like a main warehouse for people who maintain a shed of miracles.
AND A QUESTION: What is this?
It’s on the passenger side, on the inner fender, just in front of the blower motor. The truck has an aftermarket cruise control (that doesn’t work) that’s tied into this thing. What does it do?
