Marine air 16k reversing valve

My pump has a separate switch on the ac board from the switches for each unit so I can keep the pump off. What am I testing? Just ac colts at coil when heat kicks on? When the unit clicks? Should it be 110v or close?

The valve coils wires should go to the board as well. Also the compressor should too. If you can remove the compressor wires that would be good. If you can remove the wires to the coil you can put your meter across those two terminals. If you want you can face time me when you are there.

Thanks Handy. The building I am in gets barely enough 3g to get a text, no FaceTime or WiFi so I am thinking this will have to wait until I am back in the water and on WiFi. A FaceTime with you come spring would be glorious 

Handymans342

Well you can still check and report back

indeed

You could ohm out the coil too

Liberty44140

Oh, how would I do that? I’ve used a multi meter many times for volts but never for ohms 

Handymans342

Well set the meter for ohms, pull the valve coil wires off the board and put the meter leads in the connectors or wrap the wires around the meter leads. It should read 5 ohms at least. I havent ohmed one out in a while but it needs to have resistance. If the meter has no reading then its shot. You know, some people should not own a boat LOL

Sounds good! Can I do this at the coil, or must be done at the display?

Handymans342

Well if the wires unplug off the coil then yes. Display? You mean the thermostat? If so, no they do not plug into that. They plug on the control board
