2) Disconnect EHA (Y1) coupling. Positive lead to EHA pin 2, neg to pin 1. Same spec 19.5 +/- 1 ohm.

3) Positive lead to EHA coupling terminal 2, neg lead to KE coupling term 10. This tests the wiring from the EHA term 2 back to the KE controller. Spec is <1 Ohm.

4) Positive lead to EHA coupling terminal 1, neg lead to KE coupling term 12. This tests the wiring from the EHA term 1 back to the KE controller. Spec is <1 Ohm.
I ran the diagnostic and everything was normal so I guess I can rule out the EHA.

Since my last post I also replaced the EZL with a very clean eBay purchase. It works fine but made no difference in the starting bahavoir.

The last couple of days I've beeen starting it with the gas pedal depressed a little. When I do this it fires right up, revs up and stays reved up until I let it idle. Sometimes it will stumble a little when I let it return to idle others it doesn't. Do this mean anything to anybody?
