Voltage drop whilst using the electric windlas

[Assassin]

OP says it is pulling 45 amp.

I know what he said, but is he going off the specifications or has he actually measured it as often they draw more current than they state in their specifications, which is the reason I would rather clarify if it is a specification figure or an actual current measurement using an ammeter while working,

assuming my batteries are not terminally damaged
running the engine at a higher revs whilst using the windlass will help
any idea as to how fast to run the kad in neutral to get some more amps to help out ?

p.s. the 11V was a v short term drop as the windlass was turning, it returned to 12.5 same moment the windlass was switched off
i have a graph on board, can post it here if interested next week

I wouldn’t be too fussed if it goes straight back to 12.5v without any charging sources - that implies a fairly healthy battery and charge state. If the engine was still running then I would try another check without it running at all and see what the battery goes back to.

Hi Simon

I was referring to the actual measured current and not the voltage, while voltage is a useful measurement of certain failures, it is not an accurate measure and current draw is.
