Leg going into beach mode of its own accord

Does the pump continuously operate? If so I suspect a fused relay.

Temporary measure if you can drop it, disconnect the pump from electric power source?

He can lower the leg but I'm not sure how long it stays there (I don't think the pump is running continuously).

My thought is to pull the plugs out of the relays as a temporary fix.
 
Haven't ascertained that yet.

If it was a mechanical (hydraulic?) failure then surely it wouldn't be lifting when it was going forwards (force from the props would trim it in)?

I'd be more worried (I think) if it was lifting when going astern.

Ah you're right, I'm thinking about this (trim ram failure) the wrong way round, sorry.

PS easiest way to disable the trim relays is just to pull them out of the sockets, no need to mess around with wiring. Maybe that's what you meant above?

Thanks, that's what I meant (does of course mean crawling down the side or over a hot engine).

They are (a) sealed automotive relays and (b) cheap as chips so a sensible solution would be just to replace both the relays.

I've got two spare (unused) relays on board but the defective ones were from the same batch and are less than a year old. So I'm wondering about the quality of the cheapo automotive ones compared with genuine VP parts.

I'd be happy fitting them myself, my partner less so. It's also rather a tight squeeze down the side of the engine (they're mounted on the stern) so I'm not sure my partner would fit. The local Volvo dealer has lots of funny shaped blokes so they could swop them over no problem!

Yeah but even if the spares have the same short life, at least that would solve the immediate problem, no? Fitting them isn't that hard, they only go in the socket one way.

Try reaching the trim pump on a targa 34 !! Not that easy unless your arms are 6ft long

To disconnect the trim pump power the closest and easiest place to reach is the main fuse on top of the engine just behind the black fuse box
 
Thanks Paul. I've never tried to reach the trim pump but guess it's in a similar place to the relays?

I can actually reach the relays on both sides. To get to the starboard side relays I have to crawl down the side of the engine. To get to the port side relays I have to lie across the engines with my head in the 18 inch gap and I can just about reach them with my short arms. Getting between the engines requires dismantling so I don't go there.

Access to the fronts of the engines (belts, impellors, filters, etc, is great).

I shall familiarise myself with the fuses and advise my partner accordingly!
 
How did you fix it?

Removed both relays, whacked them on top of the engine block a few times, put back both relays.
I'm not sure this a valid repair technique, but it got me going again.
Then I replaced all the relays when I got back to shore.

You learn't your elec-mech skills back in the 70's on CRT tv's right? ;)
