newdean0 0 Posted August 8, 2006 Since doing my mi conversion my alternator hasn't been charging the battery. The alternator light goes out when the engine is turning. I think I might have connected the wrong terminal on the alternator, does anyone have a picture/diagram of what is supposed to connect where? Also, can the light function correctly if the alternator is knackered and do I need to connect anything other than a ground and the battery to make the alternator start charging?

dee205 3 Posted August 8, 2006 You have probably connected the live+ up to the wrong screw terminal and fecked the alternator. I've done this before. The light in the dash won't come on either if this has been the case. Damien Share this post Link to post Share on other sites
newdean0 0 Posted August 8, 2006 Bollocks, the light came on brightly when I revved the engine the first time, I thought it was the belt slipping. I've driven over 3 hours though since this happened and I'd have thought the battery would have gone flat way before this. Share this post Link to post Share on other sites
Guest 205_dave Posted August 8, 2006 +ve terminal on the alternator should connect to +ve on the battery. Alternator will earth through the engine. Best way to check if it is charging is to stick a voltmeter across the battery. Should get over 14 Volts across it with the engine running. Share this post Link to post Share on other sites
