First thing, we test all the gauges.
Oil pressure: check
Somehow lost the light that snaps in the back of it though. Hope that turns up soon.
Fuel gauge: Nope.
I had read in Bridget’s build manual that the sender in the fuel tank was to be changed to match the Classic Instruments gauge. But since that gauge never read more than three-fourths full I allowed myself the delusion that maybe it hadn’t happened. Maybe it would just work.
It went to about 3/4, clicked and fell to empty.
I flipped the leads to it and it didn’t change its behavior one bit. looked up on the innerwebs some troubleshooting tips. I’d like to formally thank Bill C.: You da Main, man!
Figured I’d run the ohm test on my sender in situ, since I know the tank is just about full.
63 ohms. Should me more like 10-15 at this level. So, sender’s no good–at least for this application.
But, as per Bill, the jumpy gauge (and lack of any heat coming off the vibrator) means the vibrator is shot too.
Pray that speedo works as advertised. I’ll find out (I hope) in a couple weeks when this job is behind me and I can road-test her.
