Trim and tilt problem?

[JIMBOB]

Can anyone offer any advise to a strange problem on my Suzuki DF70?, The trim works fine if the engine is not running, however while its running it trips the boat electrics if pressed, cutting the engine and electronics on-board, this happens if you use the tilt button on the engine and the one on the throttle. It started today and sometimes its delayed so it trims a bit then everything cuts out! Its shorting somewhere but why only while running?

I'd say damp, tracking to earth somewhere. Can be intermittent and variable. Just a thought.

 

Higher voltage when running, just bringing in enough charge to trip. Has to be damp as my first guess.

Yep, check earths for corrosion, how about the battery terminals - are they nice clean and greased?

Thanks one batterys new but the other is a tad corroded, I'll check it all over, the throttle and front console all got just a bit damp Stuck on its mooring during the recent monsoons with two smashed Windows!

Hi James

 

As a last resort it may be a bad/shorted relay contact.

James, I had a similar problem on Neo. It was one of the batteries had a poor connection, so when the trim was used with engine running, it used to dim lights and cause GPS to cutout etc. ( this happens because the trim pulls much more current than gps etc. )

Difference though was the trim worked slowly ( as in flat battery like ) when the engine was not running.

Also worth checking the main power cable (red) for corrosion

often gets a lot of internal corrosion turning the wire into blue powder
