We're having fun with "Claret" our new 2005 MS Pilot 34 Express twin, but sometimes we're not. We bought her last year and had an issue with the starboard micro commander occasionally failing. Moving from sail back to power I thought maybe it was me. My previous motor boat experience was with my 27 Donzi ZX, a simple 454 with mechanical throttle, shift and steering. The MS uses an electrical ZF Mathers Microcommander 9000 series for throttle and shift, it was new to me. Naturally caveat emptor or WYSIWYG. The dealer (MS dealer) said we needed a new command head, $700 later with a new command she will still occasionally fail.
I called Control Masters Marine Systems, Inc., distributors for the ZF MC and was advised by the tech that Mainship places a relay in the power circuit to the command unit which will fail causing the system to fail. He said to 1. either find where the relay is and replace it or 2. run a separate circuit to each command unit, both power and new ground.
While I was fortunate to have the complete MS owners manual et. al. for all systems MS only provides a color wire diagram/picture, not a real wiring schematic showing wiring, switches, relays, etc.
Has any other MS owners experienced this type of problem or know where I can obtain a real wiring schematic for a Pilot 34 twin?
3 calls to MS remain unanswered and now I do not trust the dealer, as they say once burned shame on you, twice burned shame on me.
