Charging circuit warning lights

Post by Ginjaninja92 »

Hi all,

I just got 3 dash lights come on while driving this afternoon. The battery, cat temp and engine bay fan lights. Am I right in saying this is a fault in the charging circuit? If so, could this be related to the fact I've had a squeeky belt for the past 6 weeks or so?

Faaaaanks!

A slipping belt could cause the code to come up but the reason your belt is slipping could be that the alternator is starting to seize up, which is a known problem.

Driving in wet weather can cause a loose/worn auxiliary belt to slip which would bring up the warning light, if it is the belt you should hear it screeching.

Investigated today and it turns out the belt is gone!

Must have either snapped or the tensioner has worked loose and the belt has just came off. Either way an easy fix, especially as I have a spare belt!

Happy days, thanks for the replies people.
