Hello MG Forum...
On my '79 MGB, the ignition light remains on after the key is off, and out! When this happens, the brown wires to the fuse box are hot, as well as the white/brown. If I disconnect the white/brown (signal?) wire from the starter relay (one closest to the front, maybe ignition relay) the light goes off, and stays off when reconnected, and it's not hot at the fuse box (browns stay hot). I replaced this relay (with what I think is a new one, from PO) but problem remains. I read the thread about the alternator diodes, but as mentioned problem clears as described above. (I did replace the ignition coil recently and screwed up the polarity... causing the tach to act weird until corrected.) Is this also a alternator problem, or do I need a new ignition switch, or what? (Oh yeah, PO installed after market electronic ignition, so there some weird wire splicing going on.) If you understand Lucas electronics, please help!!!
Thanks!
