Fresh Water Tank Gauge Inop.

This post is unreasonable. We are all boaters that want to share solutions to our common. No need to attack a fellow member offering an alternative solution with this personal attack, particularly after he graciously answered why it was relevant.

This is not an attack. It’s a rebuttal and an opinion.

This thread is about a fix for a problem on our boats. SBW has twice jumped in here telling us not to use this fix, but instead use his preferred method (which is costly).

The ones here that have used Jim’s fix are quite happy with it.

 

Thanks to Jim. Fixed the problem that led is always on last week. As Jim said, I replaced the four transistors. How to replace the transistor on the circuit board was learned on YouTube.

It is a logical to look at the transistor problem that all the leds are turned on even if the fresh water tank lines are cut off.

Thanks again to Jim.

 

Jim changed my transistors this past winter and it’s really nice knowing how much fresh water I have on hand again.
The first transistors kept the gauge working for 16 years before quitting last year, I know this because the original wiring harness was undisturbed when I went to remove the gauge, hoping these will do the same.

 

Jim,
Are you still fixing these boards? Mine is showing full continuously.
Thanks!

 

Yup! Send it to me’

 

Ok! I’ll pull it next weekend! Thanks!

 

My water tank Meter breaker in main box won’t stay in the on position so I can’t tell if it’s full or empty, thoughts?

 

Hello

Hello Mr Crews,
I saw your posting about the transistors that are bad on the display board. I am with my boat now in Rovinj, Croatia and my display has the symptoms that the transistors are bad. Can I ask you to let me know what transistors I should order to have them replaced. I don't know much about electronics but I am sure there are lots of different transistors... THANK YOU!! Erwin

Thank you very much - if you need something form the EU let me know. I am here for 1 more month! All the best -

 

I've got the same problem on my 2004 420 DA. I can change the transistors, but can't find the type number on them. If you have any left, I would appreciate your mailing me a few. If not, then what type are they and I'll just order my own bag with many spares.

BTW, there's a black mark on the board next to one of the hold down nuts that looks like it could be a burn, but there's no sign of burning, if that makes sense..

 

They get super hot!
I have the number and stock

 

Hi Jim
how do you tell what the problem is? when I hit the button they all turn on?

 

What is the number?

 

Post 51 has the part number

 

That’s usually the transistor problem.

are you still repairing them?
