Fuse box issue

[BamBam 87 Monte LS]

87 Monte LS...the 20 Amp fuse in the c/h port is good, but won't activate my test light. I pulled the fuse out, and tested the port itself, with same result. Can not find a wiring schematic to trace the problem. Help please

If the fuse is "good", at least one side will light the test light. I don't know what the "c/h" circuit does, but if you have multiple constant powered circuits in-op, you may want to check the fusible links at the starter.

The c/h circuit is the choke heater. My oil/choke light is on. Oil level is good. I'm new to mechanics and electrical work, so not sure what fusible link you are speaking of

That's probably an ignition circuit. Did you have te key on while testing? Does your test light work?

Yes ignition was on...yes test light works

Ok....I took a jumper wire and placed it in a working 20amp slot, then connected it the c/h slot and started my car. The light went out. Dies this mean my oil sending unit is bad?
