As the lawyers keep admonishing us, "Adit nothing!"

There might be something wrong with the wiring that made something in the computer go pop. In this case installing another one might just make it go pop again. This was the reason behind some of my post's.

The die has been cast, daveyson. "The moving finger writes and having writ moves on . . ." Stay tuned! Wear hearing protection.

Say what you mean. I’ve been trying to follow everyone’s suggestions. What else should I try?

Maybe because starter relays are expensive a lot of bricks have after market relays, with the BMW plugs replaced. The BMW plug makes it impossible for pins 85 and 86 to make contact.

There has been a case like yours where the computer wasn't sending earth to the starter relay. It had two normal connectors that were almost touching. I thought if they did, 12 Volts would be sent to pin 11 of the ICU, maybe that would make something go pop.

In the electrical section is a post something like electronic trouble shooting, it's known as Bert's guide, which describes how to check that the ICU inputs are ok (plus outputs)

UPDATE: ICU replaced with NOS ICU from eBay. Starter fired right up. Now putting everthing back together. Thanks for everyone’s help, k100-forum.com is invaluable to owning a brick.

Thanks to daveyson, Laitch and Point-Seven-Five. After putting everything back together, I’m on the road again.
