Arthur, I don't know how you knew it was the alarm relay and not the ign switch, but sure enough .. checked an had power to term #1 and if I jump 1 and 3 starts right up .. have the relay jumped for now and will get a new one ASAP (assume it is P2020-25016) ...

Sure is wonderful to have folks like yourself and others on this forum, having owned many MB's over a long period have accumulated some knowlege I will try to contribute, but my knowlege is mostly mechanical, while I understand elec, just not much experience .. your experience and know-how have been invaluable!!!!

Cheers

Tim
