Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
At this point what is known, (electronic devices are blowing including fuses and frying instruments and modules). This tends to normally point towards excessive voltage such as a system that is overcharging is one thing that can cause this problem ESP if this ONLY happens with engine running, as a battery is 12.6vdc static voltage, when engine is running the charging system should have a max output around possibly 14-14.2vdc, you get a system showing say 16-18v or so and thus can be the problem, so the first check is system voltage with a voltmeter with engine running if good say 14vdc then move on to checking grounds and other connections as well as excessive amperage and checking for shorted/damaged wiring.
Thank you!
