Sub Tank / Charge (battery) warning lights

[Orsm6]

Hi all,
started up my 01 GU ZD30 last night and while driving along the Sub Tank and Charge lights stayed on. Have read a few comments, one bloke changed his alternator and had success, but wanted to get as much info as I could. So if you know of anything could you please chuck in your opinions?

- Not in limp mode
- Has turbo timer
- unsure of age of alternator
- it does sound slightly different when idling. I know that sounds weird, but I have noticed a difference.

cheers.

do you have a mulitmeter ? checking the voltage while its off then check it when the engine is running. should give you an idea if the alternator is working.

I haven't done that as yet mate. But I will be. Just wanted to start getting some info put together :)

thanks for the reply

Had a similar thing that was dual battery system related after I bridged the solenoid to use the aux battery as a starter.

good to know. I don't have a dual battery set-up. but i'll inspect the wiring as there was a dual set-up before I bought car, maybe something rattled loose.

Classic symptom of a shagged Alternator or, if your lucky, a fault in the Alt wiring.
Check your Alt fuses, plugs etc and if all OK get the Alt tested

measured 11.7 at battery under idle. I think she's fooked. Brand new drive belt so it isn't that, wiring looks OK. I haven't checked a fuse though. :)

Found a broken wire before pulling out the alternator. In the past this has only thrown a check engine light, bugger. Time to open the wallet lol.
