I have a 1992 4 dr sidekick with 1/6l, 16V 4 sp auto. 4 wheel drive; Having a problem with the oil light not coming on at start up. Wondering where to start trouble shooting. I have removed cluster and swapped bulbs with known good bulb but light still won't come on. Can I some how check the sender or how exactly does this circuit work. I saw a description about how to replace it with a real gauge but nothing about how to trouble shoot the light. thanks
