Hi all, I have a possible problem with my alternator and really would appreciate any advice
After driving through alot of puddles and a few 4" - 6" floods last Friday, come Saturday morning the battery light on the dash illuminated about half a mile from home, so I turned around & went straight back.
Come Sunday, started car & all was fine for about 10 seconds, then battery light came on. Wipers & electric windows were slow & battery voltage (using music/compass buttons on steering wheel to display dash diagnostics) was reading 11.5 volts. After a minute or so, reading went back to normal 14.5 volts. A quick diagnostic spewed up a U1132 code - lost communication with generator. I cleared code and hoped for the best.
Driving around yesterday for about 20 miles and using the music/compass buttons, voltage seems to be reasonably steady displaying between 14.3 - 14.6 volts depending on electrical load. There are no more fault codes using my autel reader and my laptop 'appcardiag FCA' diagnostic software confirms that there is no problem & no more fault codes.
I know that alternator failure can be immediate or intermittent, in my case it may possibly be intermittent, but is there a possibility that the problem may have been caused by the amount of puddles/floods around last Friday soaking the lower engine ?....are there any connections that could have been soaked & temporarily shorted ?
Also, not really relevant, but possibly could be. Does anyone know what the black cylinder looking thing with two clips either side is on top of the alternator ? This thing wasn't clipped together properly on one side, but it is now
