Precise1 Posted March 24, 2014 Share Posted March 24, 2014 Your alternator could be failing or the connections to the alternator, battery, ground, chassis could be corroded and not conduction properly. Start with a visual inspection... B 1 Link to comment Share on other sites More sharing options...

fleurys Posted March 24, 2014 Share Posted March 24, 2014 measure the voltage at your battery at idle... anything less than 13.5v means you alty is going down... S. Link to comment Share on other sites More sharing options...
devonianwalk Posted March 24, 2014 Share Posted March 24, 2014 measure the voltage at your battery at idle... anything less than 13.5v means you alty is going down... S. This. Also, multiple dash "dummy" lights are usually an indication of a failing alernator. Link to comment Share on other sites More sharing options...
Precise1 Posted March 24, 2014 Share Posted March 24, 2014 thanks B I've been thru most connections all seem good gonna keep going over it tho ty again You are welcome. I almost always recommend inspecting and testing before removing/replacing but it sounds like you have done that. As long as wires/connections look good, the afore mentioned voltage test is the next step, then removing the alternator and taking it in to have it load tested. Thankfully none of this is difficult, but hopefully you have a garage to work in/spare vehicle for a few days. B Link to comment Share on other sites More sharing options...
byob Posted March 24, 2014 Share Posted March 24, 2014 Alternator output might be correct but the diodes are failing. Have it tested Link to comment Share on other sites More sharing options...
Alkorahil Posted March 24, 2014 Share Posted March 24, 2014 Defiantely a lack of power. Mine did that in a snow storm many years ago. I had heater, blower, rear defost, headlights, foglights, roof lights, radio, wipers all on. At a stop light, when every the delay on the wiper would trun the wipers on, the radio would cut out.....too much power draw. Link to comment Share on other sites More sharing options...
