My idiot brother connected the jumps leads to the battery the wrong way round. It was like Bonfire Night, sparks flying everywhere. We eventually got the car started (with the leads the correct way around) but now the meter on the dash doesn't read as it used to. Normally the needle sat towards the right hand side, now about 3/4's of the way along. Sometimes less if lights, etc are drawing power. It also fluctuates when the indicators are on. I've checked the battery and it's fine, the alternator is producing enough power too. Anyone out there know what damage may of occcurred...?
My needle sits towards the full (about 3/4) most of the time. When I have the indicators on it moves up and down along with the "clicking" sound Doesn't budge when other electrics are on though...
It never used to do that before he"helped"...! I thought that he may of damaged something electrically...? Not really au fait with the mechanics, just drive it with a big grin. I even got the guys to take a look when it went in for it's MOT but they couldn't find the problem either....! Looks like I will just have to live with it then, annoying though.
....this sounds normal to me too. Try holding the revs at around 3K in neutral and then put the indicators on - the needle shouldn't move anywhere near as much. If it doesn't then it's fine - otherwise the regulator in the alternator may be on the way out - not that it's worth replacing ahead of time, it's only really worth replacing when the alternator packs up completely - heralded by the dash lighting up like a Christmas Tree.
