I bought a M600 the other day. starts right up. worked fine for 2 days. today it just died. I found that the main harness disconnected. plugged it back in, started right up. but now it wont move. the lift and tilt are fine, but it wont drive. hopped off found the variable speed line broke off and was leaking everywhere. I don't know much about these machines, but is this why it wont drive at all? I thought this would just not activate the faster speed. how do I fix this? is there a parts diagram? when I opened the access panel the line was lying there broken off and the cap was off. how did the ine eve connect to the base I can slide the outer cover off nothing holding it on. What do I do???
