Teleflex throttle

[tomsboat]

I have 2 driving stations on my boat.I have a Teleflex throttle station at the lower station and one at the upper station.I was out 2 days ago and both stations worked.Today I went out and I got no power at the upper station I only got a dull flickering green light and then nothing.I tried starting from both stations and nothing worked I made sure the lower station was in the neutral position any Idea where I should look?Tom

I tighten up all connecters at lower helm though none felt loose but now the upper helm is working go figure.Tom
