I've been sick the past two days since Sunday when we did some trouble shooting on my tachometer issue, but Richard came by the coach today to help me be sure it was not the tachometer that was bad. All we had proved on Sunday was that we had wiring continuity to and from the tachometer on Sunday. He brought a 9 volt battery. He then attached two alligator clips with wires to the two tachometer terminals on the front electric/fuse panel and then began tapping one wire against one of the battery terminals......the tachometer immediately responded by reading 500 rpms steadily as long as Richard continued the rhythmic tapping. So, now we know for sure it is not the tachometer. It could either be the VDO generator, or the VDO generator drive key.....looks like a little paddle (See attached picture).
If it is the "key" then that is only a $10 part.....if it is the generator then that could run from $150 to $250. Going to disconnect the generator from the engine and use the electric drill with a flat head screw driver attachment and then spin it....if we get no signal at the tach, then it is the generator...if we get a signal then it should be the "key".
