Kinda late but i want to share my experience. I bought a used '99 Tioga a few months ago. 900 hrs on the genset. When inspecting it, the seller had a tough time getting it started but after a few tries it started and ran good. It continued to be a pain to start. It would spin once, then nothing. Spin once, then nothing. It acted like a dead battery but they were ok. After a few tries it would start. Then before leaving for a trip i wanted to pre flight it. It almost started then NOTHING. nothing at the remote and nothing at the genset. Breaker and fuse ok. 13.6v at both sides of solenoid. ARG! Starter! Searched the net for instructions how to change the starter. No luck. So, being inclined i decided to attack it alone. Contacted Anyrvparts nearby and they verified the correct starter for about $100. Started arrived the next day. I disconnected the batteries for both vehicle and coach. Removed battery cable from solenoid and gas line (plugged gas line with clamp and bolt). Removed the 4 bolts securing the unit to the frame. I built a 2x4 frame to slide the genset onto. That way i could slide the genset out at an angle without removing the wire harness and it was enough room to remove the genset cover. Removed the cover and the starter is located at the top left rear. Easy to get to. I found the problem. The nut holding the battery cable onto the starter was laying at the bottom of the genset and the cable was disconnected from the starter. I could see that the cable had been arcing (the one spin, no start issue) before it fell off. Changed the starter, put it all back together and it started the way it is supposed to. Very easy to change it yourself.
