Courtesy light Timer
This past Tuesday evening, Dan (Agent86) and I worked on troubleshooting the voltages on the Courtesy Light Delay Timer Connector. Unfortunate I could not focus mentally. Found out the next am that I had type 1 diabetis and was going into a comma. Just felt good enough today to finish up the project. It was Dan that did all the work in finding the info in the FSM.
On a 1987 Corvette L98 the Courtesy Light Delay timer is next to the ECM under the dash on the passenger side. Pull it from the connector and you will see 5 pins on the connector. The board is protected by a black plastic enclosure. You can pull the board out of the enclosure to examine it. In my case, the power transistor in the heat sink was burned to a crisp.
I ordered a new one from Corvette Central (pricey little devil). I believe there are places that one can have it rebuilt or you can order a used one from one of the Covette Junk Yard (Tampa). Before I installed the new $100 one with shipping, I wanted to check the voltages on the connector to make sure they were correct. I did not want to plug in a new timer only to blow it too. The correct voltages are on page 8A-114-5,6 in the FSM. The diagram of the Connector is on page 8A-202-8. The circuit is on page 8A-114-2. The test for voltages and troubleshooting is as described and should be easy to follow unless you are going into a diabetic coma without realizing you have diabetis, like me.......cheers

I'm type 2 and have a hard time dealing with that, can't imagine type1, time to get your self in shape my friend. Good Luck. Oh and yes I've been through the timer thing real PIA but I was lucky enough to find a new on e-bay for $40. but that was about a year ago.
