Low Current issue i think !!

Hi, this morning, things didn't seem right, rapid clear windscreen wasn't so rapid, electric windows slow. and both front heated seats didn't work.

I can only think this is something to do with the battery or alternator . i have been through a lot of flood water over the weekend, no warning lights or other issue, but anything that needs alot of power doesn't seem to be working or working slowly. my fan belt did squeal when i splashed through a large flood. it stopped quickly.

ill do the normal checks on the battery with a meter later, but anything else i should be looking for ?

Cheers
Mark

Be careful as dead alternators have a habit of damaging/draining batteries to the point they also need replacing

alternator

All booked in at john craddocks £230 + VAT, cannot fit me in until Thursday though Sad

i was wondering why the alternator charge light isn't on though.?
or does the output need to be totally dead for that to work.

Cheers

Guess you were still driving it! How long did you imagine the battery would last without being charged? Rolling Eyes
