RV Won't Start-No Spark

[Jnwinston]

Have 2000 R-Vision Condor 1330; parked it after a long trip. Tried to start it to no avail after a week, just cranks but no light off. Sprayed fluid down the intake and still no go; started gas generator no problem. After checking all the fuses and circuit breakers, they were all good. Did find a grounding wire hanging from the negative side of the battery but can't locate where it may have attached to. The engine is definitely not getting a spark and the loose wire may be the culprit. Anyone have ideas where it may attach? Also, any other ideas on how I can start the engine would be appreciated. Thank you!

Create a temporary ground with that wire and see if it solves the problem.

If it does, make the temporary ground permanent


I otherwise would not have a clue as to what your wire does or where it goes.

Well, the negative battery terminal can only go to chassis ground. Is the big negative cable still attached? To battery and chassis? If so, I don't know of any engine-related purpose for an additional ground wire.
