cubastreet Posted May 20, 2021 Share Posted May 20, 2021 My newschool 05 astra gauges all stopped working a week before wof day. The next day they started working again but a couple of days later they stopped and haven't worked for a week. I tried disconnecting the battery and I pulled the gauges and plugged and unplugged then as few times but they're still not working. The tacho motor just quivers whenever it has power. I'm thinking I'll head to pick a part and get another cluster. Can I just swap them or will the ecu fight me? Anything else I should try?

Alfashark Posted May 20, 2021 Share Posted May 20, 2021 What's the battery like? Lots of modern stuff gets the whole random Christmas tree of dash warnings/everything goes dead intermittently when the battery is on the way out. Also, likely the immo is part of the cluster and would need recoding. 1 Quote Link to comment Share on other sites More sharing options...
cubastreet Posted May 21, 2021 Author Share Posted May 21, 2021 Battery is old but starts the engine fine. I might put the charger on it just to be sure. It runs with the gauges on the back seat so the immobilizer isn't there 1 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted May 21, 2021 Share Posted May 21, 2021 Check voltage while car is running. Some modern stuff turns everything that isn't essential off when it detects low output. Happened with flatmates aurion when the battery terminal was a little loose 3 Quote Link to comment Share on other sites More sharing options...
anglia4 Posted May 21, 2021 Share Posted May 21, 2021 Could be a bad ground connection. They're always a proper PITA to diagnose 4 Quote Link to comment Share on other sites More sharing options...

johnnyfive Posted May 21, 2021 Share Posted May 21, 2021 TS or AH Astra? Could have been either at that point, although I don't have any specific advice other than getting familiar with the service info if you can find it, and getting creative to try not overspend on it...

I dunno, the one with no soul. I just googled and it's a TS. Thanks all, I stuck the charger on it and the and the gauges now work. Charging at 14.1V but if the battery voltage is low on startup, the gauges stay off. I really need to get the brumby back on the road. Is your one still alive J5 or disassembled? 2 1 Quote Link to comment Share on other sites More sharing options...
johnnyfive Posted May 22, 2021 Share Posted May 22, 2021 Well done! No my brumby is a rusty disassembled mess that is beyond my skills right now. 1 Quote Link to comment Share on other sites More sharing options...
cubastreet Posted May 22, 2021 Author Share Posted May 22, 2021 Worth holding on to, gen 1s are worth about 10k in America now. I'm glad mine is under a roof now, it rusts much slower. 1 Quote Link to comment Share on other sites More sharing options...
