Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Reported cause
In my case it was the dash voltmeter that gave away the cause of the issue after I started the car one morning and and the dashboard was alight with an array of fault lights and they remained lit after I attempted to reset them with my durametiric, Thats when I noted the low voltage (I had already replaced the battery with a fresh one so I knew that wasn't the cause).

Used alternators are selling for similar money at Aussie wreckers and quotes for supply of new alternators in Australia were just silly ($900 - $2000).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi everyone, My 2000 model 996tt is only charging at 13volts on the gauge and the battery is always going flat. Shouldn't it be charging at 13.9-14.1 or round abouts? Is there a known problem with these cars in terms of charging or could it be a simple case as an alternator problem? Thanks in advance

POST 2Original post

Don't trust the gauge, it may not be correct, check the charge rate with a multimeter

POST 3Original post

Yes, always double check with a multimeter at the battery. If the charge rate is within spec (13.5v ~ 13.9v) then you have a current draw issue.

POST 4Original post

Whilst not directly related to the original post, I thought it worth mentioning that my alternator or regulator (1998 C2) died late last year and the most cost effective solution was for me was to import a brand new alternator/regulator from the US for about $250 inc shipping. Used alternators are selling for similar money at Aussie wreckers and quotes for supply of new alternators in Australia were just silly ($900 - $2000). In my case it was the dash voltmeter that gave away the cause of the issue after I started the car one morning and and the dashboard was alight with an array of fault lights and they remained lit after I attempted to reset them with my durametiric, Thats when I noted the low voltage (I had already replaced the battery with a fresh one so I knew that wasn't the cause).

POST 5 / ORIGINAL POSTEROriginal post

Took the car to the auto elecs. The problem was a secondary alarm/tracker drawing power. Don't know why as looks like it had been on for ages. I got that removed and new battery fitted. Now back to driving and enjoying the beast.

POST 6Original post

what sort of batteries are you guys fitting? i'd like to find a good lightweight battery.

POST 7Original post

Quotes source post: 101656

Had the same issue. Those after-market alarms/trackers have their own built-in battery but once it goes flat (over time) the tracker draws current from the car battery 24/7. Removed the tracker and problem was solved.

I just replaced my battery with a Supercharge gold plus MF66 for $175 delivered from online batteries. For track days I have run the car off an odyssey pc680 and a lithium voltphreaks vpa-p6.
