Fuel and Temperature Gauges

Post by echinus1988 » Tue Jun 23, 2015 5:27 am

On my 1982 Aspencade I just installed the 7V regulator that is sold here. I am next repairing the connectors since one is already partially melted. Once I do that, is there any way to test the gauges to see if they are working other than running the bike?

When I took out the fuel level sensor in the tank, it was rusted and would not move until I cleaned and then broke it loose. I was gentle as I do not know how much it can handle before it breaks. I did clean it as much as I felt I could and it is now sitting inside the tank with some Lucas cleaner in the fuel.

Can I test the sensor from the tank? Is there a reading that I can take from the contacts on the top of the tank? Can I test and get readings from the fuel and temperature gauge?

Thanks for any suggestions and help.

The sensor operation can be tested directly by measuring resistance:
