Why Iam losing voltage
sounds like you have an alternator that can not keep up with the loads. I would pull the alternator and have it load tested. If the same thing happens on the bench than replace it.
You could also just turn on one of those items and check voltage. If voltage is good than its not bad grounds or poor connections. Bad grounds are bad and do not come and go depending on what is on or off.
The common denominator is the loads you are adding. the more load the harder the alternator has to work. If the alt is getting weak it can no longer handle all the loads but may be able to keep up with some of the loads. I’m happy to assist further over the phone at

Please check fluid level...also could be dirty/filter fluid? Try a bottle of Lucas Oil Transmission Stabilizer fluid...can be added without draining anything. Hope this helps.

1989 Bronco II smells like gasoline after I drive it. Any idea what is causing that?
If this vehicle has fuel injection which i think it could as cars in europe were fitted with cats from 92 but this is a 89 --but its american and if built to conform with californian regs then it could have a cat and fuel injection .if so check the O2 sensors as one of these faulty will allow the engine to overfuel .in all honesty i would need my head in the engine to know exactly whats wrong
