Fish finder cuts out when turn motor over?

[scott_r]

Ive got a Lowrance LMS 520 C with the GPS antenna and have it wired up to a switch up front by the steering wheel. I have the unit which draws power as well as the GPS antenna drawing power on the same switch. My problem occurs when I turn my 150 over to go to a new spot and my Lowrance powers off? Why is this happening?

Cheers!!

I'd say your voltage is dropping too much when you nail the starter. The only way to remedy it would be to wire it to a different battery. Or use a bigger battery which can maintain a higher voltage the instant you hit the key.
