We received the new b lower for the engine room this morning. We immediately set out to install it and it was more difficult to install than we thought it would be. However, we got her done and will test it tomorrow. The blower is an AC version and it is attached to the "B" subpanel. and we did not have a shore power line availab le tgo test this afternoon. The primairy use would be to remove heat from the engine room after engine shutdown. Man, I hate stuff that does not work so it was on the list.
