nevins Posted October 13, 2013 Author Share Posted October 13, 2013 Ok mate will do. It's a pain in the arse right now as this couldn't have had happened at a worst time. I'm renovating a house to move in by the 24th of this month so bouncing from house to house while sorting out my grandfather's house due to him passing and the weather ain't letting off. How long would you think is suitable for running off the battery with no fault. That way I can rough gauge the results. Quote Link to comment Share on other sites More sharing options...
Guest Roger NE Posted October 14, 2013 Share Posted October 14, 2013 If there's no fault, and nothing else is switched on (lights, radio etc) I would expect a decent battery to run the engine for at least 6 hours But if you are drawing a LOT of current (like it seems), I doubt if it will last half an hour . . . so if it's still OK after an hour, then that would suggest the fault isn't occurring. As I say, I would put your Multimeter across the battery, measuring the voltage while the engine is running, and stop the test once it falls to around 9V.

nevins Posted October 16, 2013 Author Share Posted October 16, 2013 Bit of an update. Done everything that roger said and running of battery alone it lasted for over 20 mins. Smell was still present. So connnected it back up and got annoyed so kept the thing running when the smell got stronger and held it on 2k. After a minute or so the smell started to clear and eventually went. So went for a drive with lights on heaters on the lot and the smell has not come back. Only thing I can put it down to is paint on the pulley or shaft and just needed to burn off. Will keep an eye and nose out for anything over the next few days. Quote Link to comment Share on other sites More sharing options...
Guest Roger NE Posted October 17, 2013 Share Posted October 17, 2013 I don't believe paint on the pulley would cause a smell that lasted for days, like you described . . . I expect it was insulation melting on one of your cables, or maybe the windings inside the Alternator. If you don't have the problem now, then it's probably an intermittent short-circuit somewhere . . . and it's obviously likely to return, so keep a lookout for it!

tooley Posted October 17, 2013 Share Posted October 17, 2013 ola nev just a thought i always used to discharge the cap every 6 months as i wasnt running the car a lot and it used to murder the battery. i had done that about 2 weeks before you purchased it but through the cap itself when it was charged up and running it always showed 13.8 to 14.2 on the charge going in.

Guest Roger NE Posted October 18, 2013 Share Posted October 18, 2013 He's disconnected the power feed to the large amplifier (which to be honest was the most likely culprit - especially a large electrolytic capacitor) Quote Link to comment Share on other sites More sharing options...
