Henny 0 Posted October 31, 2005 check the blue wire from the alternator.... there should be a connector down by the starter motor... if this wire has crappy connectors on it or is damaged the light on the dash will do strange things... Quote Share this post Link to post Share on other sites

Less than 13.5V with most of the electrics off and providing your battery is holding charge it's almost certainly the diodes. Not worth fixing, get a new or exchange unit. David.
