Electrical help

[Jim Hupy]

Sounds to me like cutting off your nose to spite your face. Why take an
anvil reliable system that needs almost NO MAINTENCE, and replace it with a
home brewed custom one, that only the originator can figure out?
Col Ken spent a few days here in Oregon with us, and I had a chance to take
a pretty good look at his 23 footer. Talk about complexity. Only Ken could
know his way around it. Pity who ever has the next turn on that one.

I can't believe anybody would willingly choose Molex connectors. They are famous/infamous for the female terminals losing tension and going high resistance! This leads to intermittent operation, and in the worst cases, overheating/melting of the plastic/nylon housings! And they are definitely NOT weatherproof!

Been there, done that.

Anderson Power-Pole connections have gained wide acceptance but they can have problems also if they are not assembled correctly. Individual housings (one wire) come in eleven different colors and they can be assembled into multiple conductor groups, using specific colors for each wire. I have used them for control of an antenna that has motor drives to control the length of the elements to cover a wide range of frequencies in one single array.

Jim,

It may be complex, but he does have a label on every wire he could original or added.

The common Molex connectors are only rated for VERY few connects/disconnects. Read the datasheet! about 10 cycles maximum. If you want to use something like that with much better performance look at the AMP mate N lok series. Even better are the Delphi 280 series (available from Del City and Waytek Wire. They are the connector of choice for the auto industry.

I cursed Molex connectors for my 40+ year career in mobile radio communications. The connection would become intermittent or lost because of
oxidation. Just touching the pin with a probe and the connection was restored.

There was one style of connector that was like a bent finger. The metal of the contact would crack and lose tension at the bend. We finally just
started soldering those connectors. They were horrid.

Rant Off.

Hi, Johnny.

What is PR&E?

Another chap on this list stated Molex rated at only 10 connect/disconnect cycles. I believe that! If you stick a tiny screwdriver down the sides of the female terminals and squeeze the sides together they will work fine for a long time, but you definitely will almost assuredly eventually experience high resistance in the connections.

If you are going to connect your device to power and leave it hooked up for a long time, I guess the Molex will probably suffice. However, any time you have to do a disconnect and reconnect cycle, you should tighten the female sides as above.

Heck, Johnny, I figure after being retired for over 37 years, I'm entitled
to slurring my facts just a little! I sure wouldn't have done that
when I was the 0JT officer in my F101B squadron.

Despite my apparent recommendation, I did add a chassis 12 VDC buss with
several self-resetting circuit breakers, and a modern (junkyard) 12 VDC
fuse panel for all the house circuits -- it's about 2"x2" and can hold
about 20 of those tiny blade fuse whose name I've also forgotten.

A warning to save someone from my dumb mistake: When I populated that
house panel
I used a few of those "failure indicating" fuses (an LED illuminates when
the fuse pops). A few years later, the refrigerator failed. With my
digital multimeter, I traced the voltages and found that the control board
was powered but had no output voltages. Since the ice box was still in
warranty, I called Dometic, described the symptoms, and received a new
control board within a couple of days. They didn't want the failed board
back. Which, from my standpoint, is a good thing, 'cause now, many years
later, I have a perfectly good spare to occupy GMC space. Only when the
refer. didn't work with the new control board did I go inside and see the
red LED on the fuse! Yep, the LED bulb in that "Indicating" fuse
passed enough current to make my DVM think the supply voltage was good and
I was too dumb to remember that possibility.

Which brings to mind another "old codger" tale: When I went back to
college for a 2nd degree in Electrical Engineering I had to, reluctantly,
educate the EE101 lab instructor (himself a brand new PhD) about
multimeters. Seems he'd never learned that a 20,000 Ohms per Volt
multimeter has a higher input impedance than an 11 MegOhm input Vacuum Tube
VoltMeter (VTVM) (or, these days, a Digital VoltMeter (DVM)) -- at any
input voltage selection of more than 550 volts. He eventually forgave me
for informing him of his ignorance in front of my lab-mate (a situation I
should have handled more graciously).

In the old days, 1966 thru 1969 I was rated as a 40270 Recon sensor system repair. Camera and sensor systems on RF-4C, RF-101, RB-66 and SR-71. It is hard to believe that was al most 50 years ago.
