I am assuming you want senders with Douglas connectors Smile

I have a 120 psi Oil Pressure sender and a Temperature sender with Douglas connectors on them. I will need to test them to be sure they are in working order.

Will let you know later this weekend...

I have performed the following tests and I feel these are working sensors:

Temp Sensor - I took a heat gun and applied heat to the sensor and using an Ohm Meter the resistance in the sensor changed as the temp went up and then down,

Oil Pressure sensor - connected to a compressed air source and applied 120 lbs pressure and the resistance changed then returned to normal.

The senders are with Douglas connectors...

I have sent you a PM on what I am asking for the set.

You could employ an ohm meter and record the test results IAW the TB for M series gauge testing. This would clearly make it easy to label the senders serviceable or not. We have free copies loaded to the downloads page.

Do you have the correct 24 volt electric military gauges in the dash. The military senders will not work with civvy gauges. If you have the correct military gauges then be sure to check the oil press gauge to determine if it's a 0-120 or 0-60 gauge. This determined which oil press sender you must use.

when I received the jeep, it had mechanical temp and oil gage in the panel. but I have extra correct gages with douglas connectors to replace the gages that came with it. still working on the tub so I have alittle while to come up with the correct temp/oil sending units. if not then I will put mechanical gages back in the panel until the sending units are found at a decent price. thxs
