Sydways,

I'm a firm believer in this philosophy. Never change the brakes on one wheel....

Thanks. Brad.

Worth checking the connections if you don't want to throw parts at it.

Dave,

I'll give them a whack and see if it "fixes" it, but all that will tell me is that it is definitely time to swap them out.

Thanks. Brad.

If a solenoid clicks they`re usually good. Get out the old volmeter and check for power .
I also use alligator jumpers when I`m in the bilge and don`t want to crawl over the seat .. as Walley described.
These are great for a lot of things:

Usually when a solenoid only clicks, it's not getting enough voltage.

Griff,

I will crawl up there and check now that the batteries should be charged.

Thanks. Brad.

Not sure what year you have but my 1990 Bravo One trim pumps have an odd looking 110A fuse at the solenoid. I didn't realize they were fuses initially.

See item #20.
