Trim Gauge Stuck

Has anyone else experienced a faulty trim gauge which shows the engine as trimmed fully out all of the time? This started a few days ago and was fine beforehand.

This engine is new Suzuki DF70 and has 30 hours so I hope that it's not faulty already.

Wiring all looks good and I suspect it's the trim sending unit. Although am not sure how to check it. Any advice welcomed!

The trim sender units are fairly basic bits of kit. Trim the engine up. On the outboard saddle you'll see a plastic lever (sprung loaded) with wiring, etc. With the electrics switched on, if you depress the lever the trim gauge should replicate. Possibly dirty contacts or broken switch. Check wiring with multimeter at gauge end to see you're getting 12v power.
Is that with or without VAT?
