I was wondering if I damage anything electrical if I start the coach engine while hooked up to shore power?

Actually driving away with the shore power connected happened the first time the PO took us for a test drive in the coach I ended up buying. He was making all kinds of claims that it was ready to drive cross country etc. He was going to drive first to get it out of the driveway and went a few feet and it died! Would not turn over when he tried to start it again so he hooked up the shore power cord again and after awhile got it started. Put it in drive and started out the driveway again and took the power cord down the street several yards. Luckily he had it plugged into an extension cord and did not pull lose before he noticed it. Eventually went for a nice ride.
Lesson here, don't tell how good the coach runs to a prospective buyer until they actually have a successful ride in it at least beyond the driveway (hopefully without the power cord).

Depending on which type of converter you have in your coach, StatPower/Xantrex, buzz box or Progressive Dynamic’s, you could cause the overload fuses to blow. The StatPower unit that I have had for years (1999) and it works well until I do something like starting the coach without unplugging the coach, you can blow one of several internal fuses and lose the ability to work as a converter/charger. I have done it twice, the first time I was unaware of the output fuses that on most of that brand are mounted internally and you have to take the top cover off to replace. The second time about 3 years ago there are several fuses that are mounted at board level and I ended up taking it to a factory service place in Tucson. I have not used a PD unit so I do not know if the same condition exist.

I've been using Progressive Dynamics converters for about 15 years now. I
lost one when the power company zapped the RV park several of us were in
near Orlando. It cost them several converters, as well as several
microwave ovens. That's the ONLY problem I've had with those converters
and I've started the engine while plugged into shore power, and with the
generator running, many times with no ill effects. I'm surprised that
anyone has had any problems.

Me Three on starting with the PD9245. Never had a problem.
Now understand, that most coaches, unless the wiring is changed, have the converter on the house bank. The engine bank is not connected unless using the boost.
