Tank Monitor
- Thread starter mytime
- Start date
First of all:
1. What are the symptoms of not working .................. always full, never full, power on, power off ? Be specific.
2. Which tank ?
3. Brand name and model of the monitor. Hunter Marlow doesn't make gauges.
And then we can be all over it like a cheap suit

I would pull it out and see what type of sending unit you have to start with. If its a traditional ohm based, then you can measure the resistance at various positions to see if its working. The one in my 2005 Hunter 33 was not the ohm type. Here is my experience and solution:
6 wire fuel sending unit - what is this?

Just when I thought I had fuel sending units figured out, I come across this in my 2005 Hunter 33-2. Not sure how to test it or what to replace it with. There are 3 wires coming into the connector from the boat and 6 wires coming from the sending unit. There are 0 ohms between two of the six...

The fuel monitors are known problems. I forget the OEM but they weren't very good. Search the threads here. Mine had a float, I think. Search the threads here. The OEM should show up. You should probably keep track of engine hours for your fuel consumption - figure .5 to .75 GPH. Here is a list of related threads:
I did this repair on my 356 earlier this year. In my case, the display unit turned on but showed empty for the holding tank. I replaced the external sensor and everything works great now.
For the price, I'd replace the sensor first and go from there.

3...Not sure on brand but is Standard issue from factory seen on other Hunters
Most people refer to a Tank Monitor as the name given to a Holding Tank or Fresh water tank monitor
Fuel Gauge is what I would have said if I was referring to the fuel tank monitor
I didn't think it was going to be such a challenging question
Yes you are right I should have posted a picture
Your boat has several tanks and they all have a name ............... only way us dumbasses can identify them.
But all that aside, we're off to the races. The Brand of indicator is a WEMA which is a UK company. The most likely level sensor (located in the tank) is a float mechanism which changes the resistance of the sender as the position of the float rises and falls. See attached.
Before you proceed with removing the sender from the tank, I would suggest checking the meter (what you read) for a 12V power supply. From what you have described, this may be your problem. Let us know and we'll go from there.
Yes, a very challenging question without any information as to how the gauges perform. Now that we have some details, I can almost smell blood in the wind

Thank you....running the boat home in a few weeks.... will troubleshoot and report...I was thinking it may be a common problem....All Good Ralph...
