Tilt / Trim 50A CB - 2001 GXi-A ... where to look?

[Kosmofreeze]

I know this is a long shot, but I'm running out of ideas. My 2001 Chris Craft Constellation 26 with a VP 5.7GXi has new tilt/trim issue. I was getting it ready to put in the water and everything electrical checked out GREAT after the long winter nap. Then just hours before launching, the tilt/trim quit working. Relays click but no motor run. I suspect that the 50A circuit breaker popped. Of course the pump/motor is nearly impossible to get to (port side at transom). Schematic says there is a main 50A circuit breaker for motor power - it should be in a serviceable location .... shouldn't it? None of the resources that I have speak to the location of the CB. CC only built about 100 of these cruisers, so there probably aren't many left and documentation is sparse.. My boat has less than 400 hours on it and has been extremely reliable for a 25 year old boat.

I see lots of similar threads - I'm not only one that has been stymied by the "hidden CB". My hope is that a forum regular might have some familiarity with this boat or have some tips on locating the tilt/trim CB on this vintage of cruiser with VP duoprop power. I've tried tracing the wiring from both sides (battery/starter forward and reversing relays backward) but access for my 260lb body is really shitty - no joy.

While there's circuit breakers mounted on the engine of the 50-amp range for engine items, in looking at some parts catalogs it appears you may have blade type fuses vs a breaker button at the pump area itself...Also could use your transom model number to locate your design pump as it should be something like TSK SX-MDB for example... And maybe your stern drive numbers such as SX-? (<M), etc. as those 3 model numbers separate parts look up from each other depending on what is needed with Volvo pentas.

But the following parts catalogs should narrow things down a bit for you too,

Photo of your trim pump?
Were the battery cables messed with and forgot to reconnect a trim pump power wire of sorts maybe?

Appreciate the good tips and catalog refs. Unfortunately none of these show in sufficient detail the location of the reset breaker. The fuse box reference looks just like mine, but no 50A breaker is to be found there. The trim pump details look just like my set up too, but no 50A breaker there either. The attached schematic shows the pump power is protected by a 50A reset breaker the location of which still remains a mystery. The funny thing is the tilt/trim was working fine just hours before my wife stocked the fridge and liquor cabinet! She might have bumped the trim switch when cleaning up the helm????? I'm on the schedule with the local VP shop next week ... I give up!

Have you seen post number 9 or the following thread that may help locate the breaker,https://forums.iboats.com/threads/outdrive-trim-pump-where-is-the-power-source.740671/#post-5623324




Also zoom in on the engine cannon plug connector to see a breaker mounted there on another almost similar engine model,

Awsome - I bet that's what I'm looking for. I wish the pic had some more landmarks, but I don't feel like I'm shooting in the dark now. Many thanks.

The system is simple. The relays are used as a reversing contactor .

Check the relay sockets for power. The motor A/B wires will be connected to the 30 pin on the relay. One relay will be wired with pin 87 to power and 87a to ground. The other will be wired pin 87 to ground and 87a to power
