<p>I'm late to the party, but I stumbled across the AVC1 while looking over various B&C offerings. I note it is not listed as compatible with the Jab alternator. The Technical Manual states "Alternator Stator winding overheats when pushed too hard (incompatible with shunt-type regulator)."</p>

<p>One of the reasons my progress is so slow is I spend too much time reading about all the amazing aviation goodies out there ...</p>

<p>Focusing on avionics installation now ...</p>

<p>The crowbar should be opening a fuse or circuit breaker, not smoking a ground wire. I'd check the wiring of that circuit.</p>

Luckly It wasn’t toasted. The wire going to ground was. I tried running it without the crowbar, no tach or alternator. I replaced the wires from crowbar to ground and the master switch. It works, I flew it home a little over 6 hours but I will replace it. After I landed at home there was oil all over the bottom of the plane, broken thru bolt #5 cyl. Most expensive trip I’ve ever had

<p>It seems to me that the crowbar is a safety device to prevent an over voltage condition if the VR fails. I have a suspicion that your crowbar is toast and I think you may be better off with it completely disconnected.</p>
