FIng power trim woes

[nugent]

This has happend 3 times now,,,

Gearing boat up,for the morning,, poxy no trim down on control end,, stripped it all down switch works fine, power in and Out both toggled sides,
also checked resistance green and blue wire from console to engine all good, put it all together works fine 1/2 hr later nothing again,,,


Is it simply the switch or am I missing sumat,, it still trims from engine at all times so not a solenoid,

Getting all set for running two new cables and fitting a dash mount switch seams the easy option,, now it's fekin raining lol

I had exactly the same problem. Turned out to be a broken wire in the loom between helm & engine. Depending on where the engine was trimmed determined whether it would work or not. The break was in the corrugated hose between the witches hat & engine, as the engine came up, it moved the wire & broke the connection. Wiggling the hose got it to work intermittently. Try having someone at the helm pressing the trim buttons whilst you wiggle at the transom,ooer.

Plus one for a loom break

I would go for a high resistance joint / break somewhere, could even be the switch, you can get low resistance with no load but when you try the trim switch and put a load onto the circuit it becomes high resistance. you could try just touching the connections together at the switch to see what happens, would rule switch out and confirm bad joint / connection in the wiring loom

Grrrrrr.


Still not sure. Got to be a wire break,,, Going to run a new3 core cable and go from there ,
will not stop me using it in the morning my opo. can trim it don hanging of the transom, best strap him in, hate to use him as chum bait

Agree about wiring. Had the same fault with my Twatsoo, it wasn't a break, but corrosion. Why they don't fit tinned wiring as standard beats me!

I did a continuity test with a multimeter to confirm. Stripped in new tinned cable instead of paying £200 ransom for new loom. Sorted!
