P38 throwing a tantrum?

Paul Coddington · 2024-11-28T10:42:18+0000

Hi All, it's the P38 DT with a manual gearbox. So apart from the ongoing ABS issue which is awaiting a space at the mechanics.
I've fired it up this morning just because it looked like a snowball. And no instrument panel! Checked fuse 1 which was fine, reinserted it and the panel has partially come to life. I've got a message electrical fault, fuel gauge fault etc. Rev counter is working. Then all of a sudden it sprung back to life. Now I changed the battery at the weekend. And it did a very similar thing. Any ideas, I'd like to sort this before it can get worse.

Did you charge the battery before fitting ?

Was the car humid inside, windows misted up?

battery terminals dirty or loose. Have found the positive terminal connector needs to be pushed right down or can work loose

No, I didn't. I got it from a company I've used a lot over the years. Never been an issue before.

Just checked it 12.53v. Interestingly the instrument panel is now fine. All the warnings lights, fuel gauge working fine. The electrical fault, airbag fault messages have gone. It's never had these issues before the battery change. It's been out in much colder weather than this morning, so l have no idea what could have changed.
