Restoring Rusty

[Gregski]

one thing I did not bother mentioning is that my beloved new Summit digital oil pressure gauge stopped working after only 2 weeks of service, we was too busy chasing engine noises remember

anywho, how do you test this puppy, well it still turns on and shows 00 so the ground is good, and the power is good, and I even re wired it to the sending unit, so what gives?

so lets test the sending unit, apparently you can use your MultiMeter set on the sound wave symbol sign thingie, continuity they call it, well all that means is do you have a connection, or is it broken

you start off by tapping the two leads of the meter together and you should get a reading of 0 and the thing should beep or buzz, than you connect it to your sending unit, it don't matter which end goes where, there is no polarity, you connect one end to the housing (housing usually is ground) and the other lead to the connection tip, and in our case we get no buzz and a reading of 236(ish) that be bad
