I'm getting close to a 'running chassis' and looking for an easy way to wire up the oil pressure, and temp gauges. Right now I have no wiring. When I got the engine first running, it was with bare minimum wiring - excluding all gauges.

I now want to be able to run the engine and determine A) which gauges/sending units actually work and B) how the engine is running (oil pressure, temp).

Was the 3a originally 6v or 12v? When I got it, none of the gauges were wired, and the PO was using 12v battery. Do I need at least a regulator in between the gauges and the battery?

thanks

Thanks, but i'm dumber than a stump.

The engine is the F134, not an L head....so that tidbit of info just might be important....

JB, 
What Bill said.  Pictures will help us get you going.  To test your ammeter, you will have to hook up the regulator...unless you are running an alternator.

Thanks guys - I'll work on pics. Right now there is nothing. The body is off and all the gauges are still in the dash. I believe it's an early F head ('54).

Yea, I figured I'd just jerry-rig some kinda mounting for them.

Charging system is a 65amp alternator, but don't have regulator. I was just looking to get the engine running and test the oil pressure and temperature gauges to get some feedback on the engine and cooling system. I'm not looking to wire the whole thing together just yet. Lots t do before I get to that stage.

Here's a picture of How the Temp. sending unit mounts in a 54 F head.

Good ideas F Bill.

Here's what I have: I think this is the oil pressure sending unit. Not sure if I can or how to use this piece. I've seen replacement units, but not sure how to connect the sending unit to the gauge.


This is the temp sending unit (I think). I tried to use a replacement unit (for the Fhead) but the temperature sending unit did not fit in the threaded hole. It was too big. Is this the right spot?


Lastly, here are the gauges in the dash. The chunks in the oil gauge I think are what's left of a gasket maybe? The Temp unit is in a box somewhere....

You can see how I couldn't pass up buying this jeep...it's got less than 3500 miles on it!!

Matto - looks like you and I were posting at the same time. Your pic is spot on to what I have. On my replacement gauge however, the nut is larger than the threaded hole. Maybe they sent me the wrong one?? I was careful to order one for the F Head...
In this pic the red arrow is pointing to a brass part where the old sending unit screws in. Is this suppose to be removed? This is what is blocking the replacement unit. It won't thread into that brass(??) part, but looks to be the same size. I does not come out when I remove the other piece. Is this suppose to come out too?



GG - agreed, I would like to use mechanical gauges if possible.

Agreed. I have a mechanical temp gauge (and thx to F ZBill - a solution), but unable to find mechanical oil pressure. Is there such a thing? Do you have a line on where to get one? Less electrical wiring = better for me.
