Mercury outboard controller alarm

[Duke01]

One of my many projects this year on my 1978 V20 was relocating my batteries forward to offset the weight of my new 10hp kicker that I added for trolling. I completed the wiring yesterday, everything seems to work properly but now I have an constant alarm (?) Going off in the new controller that was installed a couple of months ago.

Checking the Guest switch wiring diagram, everything appears to be correct. I was pretty careful with labeling wires etc.

Any thoughts regarding a potential cause for the alarm?

Thanks as always, Duke

Is the alarm constantly sounding or is there some kind of code beeping? :head:

It is a constant alarm - which I discovered tonight is the temperature sending unit on the engine block. Just need to find a new one online and then I can put this issue behind me.

Thanks Duke:clap:
