Lowrance guru
 

Looking for a local lowrance guru..........
I cannot get my NMEA back bone to pick up two fuel tank sensors........

worked once then poooofffed on me.

What model Lowrance do you have?

it's the gauge.....I am using the LMF 400 with a DF 300 Suzuki

I had similar problems with the same setup. What batteries are you using? Do you have at least 1000 CA?

I was running 850 CA batteries and the gauges would work for one trip, then they went out. Once I changed over to bigger batteries, they have been working great.

thanks I will look into that..........
it pics up both EP 15's but will not read one.......it sees it but will not read it........wierd

EP 15
 

Exact same problem I had. Mine would read the stbd tank but not port.

Also, you can do a quick check to see if either the tank level sensor is bad or it's the EP 15. Disconnect the 2 wires from the tank sensor and touch them together. Your gauge should read full. If it doesn't, then it's probably the batteries.

you running two engines two tanks?
I am one and two......

Tank one and tank two.

gonna fool with it this afternoon AGAIN

I'm running 2 engines/2 tanks.
