Title: Battery Light On
Post by: less on 04 June 2008, 22:05:18

Evening all. Out driving tonight when battery light came on.  :-?
Everything else seemed normal. Got out and checked auxilliary belt - all ok. Restarted to make sure it still 'had the hump', sure enough battery light still on.  :(

My immediate thought is alternater goosed, anybody had this caused by something else (blown fuse etc)?

If you have a multi-meter handy ... check the voltage at the battery both engine off .. 12-12.5 V and engine running .. should be 14-14.5 V.

Also check battery terminals for tightnes and signs of overheating .. if they get hot, take them off and clean everthing properly.

Voltages checked, definitely not charging at all.

I've checked with stealers and exchange unit is £100 ish +titfer on TC.

Just had a look under the bonnet, not much room to get to alternator, is it best to attack it from above or below? (I didn't see a how-to in the maint guides).

I'd appreciate a little guidance from somebody 'in the know' if possible, thanks guys.

I'd be looking at the brushes & armature (or is a comutator :-/) first before I condem the alternator. ...... After you've removed the bu66er though! ;D

Theres a  "how to" in the maintenance guides on resurrecting alternators ...  might be worth a dabble before shelling out more than a ton of readies .. :(

Thanks for your responses guys.

I took the plunge friday night and removed my alternator. What an absolute git of a job!!!!  >:(

I decided to go for a 'new' unit to avoid having to do it again in the near future. Exchanged at the stealers and installed, all is now working again.

If I get the time, I'll jot down a step by step guide (I wish I'd had one available before I tackled mine!).
