M FWIW .... My '84 has never exhibited the phantom flashing problem, but the '85, from the day I picked it up a year and a half ago, did. Initially, it would just flash far too long on startup .... no matter what the weather. After I blew (and replaced) the head gaskets, which meant cleaning grounds and fiddling with wires and such, it now only does it on rainy or extremely humid days. Only rarely will it start flashing while driving (the coolant level is fine and there is NO air in the system). Several months after the head gasket job, I replaced the sender in the expansion tank (its threads were bad) but I see no change to the phantom flashing behavior. I'm convinced its in the wiring somewhere .... maybe at a connector or ground. Sometimes (rainy day, remember) I'll start the engine and after watching the flashing for about a minute .... if I turn on the headlights or the blower motor (heavy load) the flashing stops immediately. Go figure. Anyway, that's why I suspect a connector or ground .... it's probably seeing too high a resistance. Mike '84 GL 7 pass '85 GL Westy |
