I have an older horizon 900 vertical windlass
(later taken over by lewmar). I bought her used and ran all new wiring
above spec and she ran great hauling chain like a dream for two years. I was told she was rebuilt just prior to purchase
. Recently, she runs well for a minute or so and then slows, then stops. At first I thought it was a battery
issue and have replaced the batteries
. When she slows I've tried switching to a fresh battery
with no effect. If I wait a bit she turns slowly then stops again. Interestingly, if you hold the chain and the bow pulpit (grounded), and run the windlass
you get a bit of a shock. My working theory is that the motor
has a short, she gets hot, and can't get the current
she needs due to increased resistance. Reasonable theory? Is a replacement needed? Any thoughts on how to trouble shoot or "just" replace?
Any insight is greatly appreciated!
