EST Wire

[pomai]

When I disconect the EST wire, the motor doesnt want to stay running. I can't keep it running long enough to set the time. Any ideas as to why this is happening. The chip is from Tbichips.com

So I set the timing to 20 degrees with the EST wire conected.

Thanks, Ed

Since you reset the timing have you tried to disconect the wire again?

If you turn the dist. so it will run when you unhook the EST wire, you will be able to time it the right way. It's impossible to time it with the EST wire connected......accurately anyway.
