Hello Everyone
If you have electrical problems or gremlins on any vehicle, here are the first three generic steps.
#1. Test the battery.
#2. Test the alternator.
#3. Replace all vehicle fuses with NEW, do NOT test them!

Now you are ready to go on with the serious diagnostics.
Roughly three of every ten vehicles with electrical problems or gremlins are fixed in the first three steps; you could be one of the lucky ones.

Have a great day.
