Re: 85hp 73mod johns gray wire

I have no idea what that RED wire is that you speak of, but the GRAY wire, if it's the GRAY wire leading from the factory engine/instrument cable, is the sensor lead that would normally be connected to a tachometer sensor terminal.<br /><br />If no tach exists, the GRAY wire would be connected to nothing other that a connecter that would normally be connected to a tach!<br /><br />The GRAY wire at the engine is connected to the terminal strip at the engine which has a YELLOW/GRAY wire attached, which is turn is attached to the Rectifier and the Stator.<br /><br />If that RED wire has voltage applied to it, and the GRAY wire is still attached to the engine terminal strip as it should be, that will destroy the charging rectifier.<br /><br />I'd strongly suggest that you obtain a service manual for that engine so as to avoid a expensive mistake.

thanks for the reply...the red wire in the box is the positive lead from engine(battery+) to ignitionswitch...then we know why he gets a dead battery.....the former owner has done some "clever"work... ii will try to get hold of a elektric scedual...ups..bad spelling... thank you.
