volt regulator / fuel sender ???

[siii8873]

I'm working on testing my gauges befor assembly. One question I have is on the voltage regulator. There are two connections marked "I" and "B", which connects to the source and which to the gauges? Also on a test bench does the case need a ground reference (ground case).
I also tested my fuel level sending unit and it measures from around 30 to 200 Ohms sound correct?

Thanks

I = Instruments, B = Battery.

Can't tell ya what the correct sender ohmage is as mine was open, so I just replaced it.

Make sure you have the correct sending unit to gauge, if they are mismatched, then it wont work right check out THIS THREAD
