Re: backfire issues

That's a strange combination of effects, but it could be  ashort in the 
charging circuit. 

That could potentially cuase a drop in voltage to the guages, and to the 
ignition, which could be causing the backfire, due to a weak spark.

You can eliminate that if you disconnect the alternator, then try a run.

Good Luck,
