Break Down Description: Friday 10/22/04 noon stopped for lunch on Natchez trace at miss./Tenn. Border Could not start Engine to go on to Nashville.
Symptoms: Engine would turn over at normal starting speed but would not start. Acted like it was not getting fuel but would not start. Called road side service but wrecker was too small to tow M/H. Mach held rag soaked in gasoline over intake, engine would start and run for a few seconds. (please don't try this trick as it looked very dangerous to me.) I found One in line Fuse holder From Chassis Battery's but it was good. engine would still not start.
Effect:Saturday 10/23/04 afternoon late Tow company sent big tow rig and towed M/H 150 miles to Nashville Fraightliner garage. Rig sat all day Sunday 10/24 Finally late Monday 10/25 after noon the tech started to work on M/H. Tried to start engine but would not start, Disconnected wiring Harness from engine computer Inserted cat shop diagnostic computer into Harness Engine starts and runs like brand new. Reattached chassis wiring harness and engine would start bur shop computer said it was getting very low voltage (about 7 to 8 volts) Shop Foreman was not satisfied they had found problem and I was not satisfied ether. I gave them Two Hours labor to see if they could find real problem.
Cause: Fraightliner M/H tech found Two more In line fuse holders that had fallen down behind Chassis battery's (if I had seen the holders I would have checked same) holders were full of water and fuse (15 amp and 20 amp) spades were corroded so bad that engine computer was getting low voltage. Fuse holders replaced new fuses and holders filled with dio-elect grease to keep water out in the future.
Outcome: Engine ran perfectly 2'200 more miles to get us back home with out a hitch.
Cost: Insurance tow 150 miles (Mad at insurance co because it took a night and 1 day to convince them we needed a big tow rig with a 10 ft reach to tow M/H to nearest shop that would work on M/H's.)
$731 parts and labor
$200 Motel bill
Update: Called Monoco "Beaver" Motorcoaches and they went back through there records and run me a copy of all the electric schematics for my coach. People at Monoco Company were very helpful and went out of there way to find schematics for my 7 year old coach.
