Joe....The odds are very good that is what's happening. You might want to be sure the radios are turned off when jump starting or better yet, like in the previous post, move the power source of the ignition and radios to the battery, which will asorb the voltage spikes. It took me a while to figure this out also, only about one in 300 of the Runtz voltage drops would be affected. Because they are solid state I finally narrowed it down to the Flathead F*** cars and trucks having the most failures. Their solenoids create a nasty voltage spike when they get some age on them.
Stray voltage spikes have also been known to zap an electronic ignition module now and then....just for future reference. Randy
