Hi

Im new to this fomum but not to skierschoice, I use to have a Moomba Mobius and I just bought a 2001 Santera and the fuel gauge its not working I bought the boat preowned so i dont know what the problem is so I will like to know how to check if its the guage or the floater and also how to remove the floor that is over the fuel tank so that way I can inspect the cable and the floater? Also my wake plate only goes down to halfway betwen 25 an 50% is that normal I belive it should go up to 50% can it be that it need a little more oil?

Thanks

Since the fuel gauge is just a volt meter, fill the tank, take the two leads off the guage and measuser the voltage it should read close to 12 volts -- if it doesn't then your sending unit is bad, or your connections are bad.

I'm not expert... but where does the voltage come from? My sender (I think) only has a postive and ground going to it.... ?? I always figured it was somehow based on resistance.

It is based on resistence. The lower the fuel level the more resistence so less voltage gets to the guage and the needle goes down. The voltage comes from the positive going to the sender. The electrical circuit is a loop from the sender to the guage then back to the sender.

What if you have 8.64 at the sending unit and 8.64 at the gauge, do you think it would be the gauge not working. The tank is about 3/4 full.

It probably is the guage then. What does the guage read?

I think you found the problem -- it's the gauge.

PS: Make sure the male fittings at the guage are clean.

Will do. The new gauge will be here on Wednesday.

Well, I had to also change out the sending unit. Now I can venture away from the dock and know how much fuel I have.

Yeah, they do that. There's my contribution for the day.

With today's gas prices maybe it's better not to know how much gas you're going through.

This has been my theory this season. Gas gauge was not hooked up after my rebuild.... I just fill it up every time I'm headed out. Glug glug glug.....
