Wiring harness for my 2000 crusader 7.4 MPI on tiara 3100 - Rob@brennanemail.com - 08-11-2018
Hi all, I’m looking for some help. I bought a 2000 tiara 3100 with twin crusader 7.4 MPI. At of the survey, it was identified that the starboard engine alternator was not working. Seller had it replaced (as well as few other things) and I signed papers last Friday. That same day, I took the maiden voyage from cape cod to Warwick RI. About 5 minutes into it I thought I smelled burning wire, but it quickly went away and we wrote it off as coming form the shipping yard we were passing.
30 minutes later the starboard engine stalled and the ignition fuse tripped. After a few minutes, the engine started again and we continued (after the broker and mechanic told us it was fine and to continue and have it looked at in RI). It happened again an hour later and we inspected the alternator to see the pole was lose and the ground had burned, melting a few wires nearby.
Drove on one engine until we hit the marina, then used both to dock. Went down the next day to swap the ground and saw the entire harness was melted as far back as I can see and the alternator post is actually very loose.
Had two mechanics inspect it to get estimates and both said the entire harness needs to be replaced and that it was a result of the wire arching due to the lose post and ground.
Of course, the harness is next to impossible to find and I am at a lose.
The part number for the original harness is 49028, but crusader no longer makes it.
Anyone have any suggestions for getting the harness or recommendation for someone to custom make one? I have owned my new boat for 1 week and it has been dead since the first day.

Rob; I feel your pain! We picked our new to us Tiara in June. Since bringing it home to Wiarton ON in June, we have not had it out until 2 days ago. Then it happened again- an autopilot failure! After 2 hours of being totally unable to steer at all, I called a Pan Pan on the radio. that attracted the Coast Guard Radio and Cutter and several others. After 2 hours of trying to get the Raymarine AP into Stby mode which is absolutely needed for manual steering, it finally did enter Stby and we were able to steer manually. By then the CG Cutter had almost arrived to tow us as well as another vessel. I was afraid that we could not be towed at all; our rudders were stuck in hard over port. This would have been a major problem to move the boat at all, even by towing. So we proceeded the 25 miles home to our marina under our own power. We did make it home........in spite of the fact that our 2 Ray marine gps/plotters failed to keep a fix on our position. Garmin I am coming' to get you!

Have you called Crusader to inquire who might be making a replacement part? Might be worth a shot.

I have, they were unable to help. I found a local person on Craigslist who builds boats and does marine electrical work. He is going to come look at it his weekend. Plan isn’t to see exactly what was damaged and build new.

ALWAYS have an autopilot power switch installed next to the control head for just such failures. You are not the first person with this problem especially with Raymarine autopilots. Capt. George
