|
|
Which wires are supposed to be secured with the harness clip on the back of the right side (when looking at the panel installed in the jeep) of the instrument cluster panel on the M38?
Also, on the back of the left side of the panel I have what appears to be a circuit breaker. I've got the 3 breakers on the battery box wired properly. Is this an extra breaker on the back of the instrument cluster panel?
I've got all the gauges wired up properly and was just checking on these two points before I go further.... _________________ Tony Morreale

Yes,
There is supposed to be a circuit breaker on the backside of the gauge panel. This circuit breaker was discontinued in April 1952 at around vehicle SN MC65043.
There should be a spider harness on the back, there are several wire loom clips, one goes to that I believe.
Do you have photo of the clip to show the location? _________________ Ryan Miller

I'm glad you explained that. I have the same instrument panel with the three circuit breaker bracket on the battery box also. So wire #11 from circuit breaker on battery box feeds ignition switch, then from ignition switch wire # 27 feeds breaker on instrument panel and then on to the gages. I had it wrong and thought the breaker on the inst. panel was one that I didn't need. _________________ Tropical Veteran

Thanks Wes. Glad I asked... I had #27 from the switch going directly to the spider harness. I'll re-route it through the breaker. Luckily I haven't put any juice through the system.
Since I'm using a solid state regulator and a Batt-Gen gauge the #8 & #9 wires would be unused making the spider harness the only connection to this gauge (since it's only got one connection) correct?
I'll take pics of the rear of the panel and try to post them tomorrow. _________________ Tony Morreale

Tony,
Here is a shot of the dash wiring from a 51 M38, but it does not really show the wiring clips very well.

Now I'm confused, which is not unusual for me and this project.
What do the 95 Ohm connectors do and are they necessary? From what I can tell, my M38 didn't have any originally and the pic that Ryan posted above doesn't seem to show them either. Are they related to the use of a solid state regulator?
Wes, and Ryan, I'll email you pics of the rear of my instruments as I do not have a photo sharing page or a gallery at present in order to do the proper linking.
As always, your expertise and help are greatly appreciated... _________________ Tony Morreale

I didn't notice the message at the top as I was navigating the large scans. I can't get them to fit on screen and can only see them by scrolling left-right and up-down to try to take in the images. My dash plate is #56957 engine MC97051. _________________ Tony Morreale

Tony,
There is more detail on those large scans.
You can condense thier size by saving them as a file and then
looking at them with a photo program.
The external resistor gauges were a very early M38 item.
They were not used on later M38 vehicles. _________________ Ryan Miller
