, controller, or a defective solenoid (these often fail) are all possibilities.
The voltage under load is a very powerful test. If the anchor winch
is receiving a low voltage under load it cannot function normally. This immediately removes the winch
and brushes as the cause of the problem.
On the other hand if the voltage is OK the fault must lie with the winch (and the brushes would be at the top of the list). A simple test that immediately separates if the problem is in the winch, or not, is a great diagnostic tool. (There can be some rare cases where a mechanical problem with the winch (such as broken gearing) can draw a lot of current
and drop the voltage. These problems are rare, but monitoring the current
with a clamp on ammeter is also helpful)
It is worth knowing how to bypass the solenoids as these commonly fail.
There are a lot of cheap
ebay wireless remote
contols. For the low cost (about $15 with two handsets) they are a bargain. They are very useful in a situation like a med moor with a small crew.
They are poorly made, so don't expect too much, but providing you have other means of operating the winch (a wired remote
and/or a foot switch) and turn the winch off when not used they are a great addition.
The only drawback is with even a brief button press a foot, or more of chain is recovered, which makes "parking" the anchor
