Winch slow when using wireless remote

[cobolt]

Not always, it was sold with low current switches too, either single direction or reversible. I'm sure the only option with the heavy duty switch was single direction, hence my question regarding the number of switches.

It was, even dual-direction.....at least until a good half way through it's sales life-span...can't remember exact date of change-over any more.

We need a model number really though, SL used so many Sprint names/numbers.

There were a few different models of the "Sprint", some were low current switched with contactors and others had the heavy duty switches. My memory is also a little rusty exactly which ones and what years, but we're in full agreement that Daves must have the heavy duty switches.

Absolutely, I'm convinced he must have HD switches.

I may have edited my comment whilst you were typing. You're absolutely right, there were many Sprint versions...SL went essentially from high-current switching all-round, to low-current+contactors almost in a "one hit" changeover...in production at least, of course the date is messed up by stock that was in warehouse and stock in distributors/retailers.

It was always a nightmare offering support to SL customers who called Lewmar as there was so little documentation of BOM changeover-dates and such that invariably the customer had to trace wires themselves...date of supply/purchase was barely ever of any use in determining what they had on board.

I think (that is think) that it may (that is may) not have the heavy duty switches as here is the wiring and the wires to the foot switches are not that large.



Although I could be wrong!

 

[cobolt]

Hmm...that's a contactor all right! I can't check wiring as on phone screen...hopefully Paul might be able to spot any obvious mistakes if they're visible in the photo.

 

[davethedog]

So, the plot thickens!!!

 

[davethedog]

Wild card though here, have I connected the positive for the remote control box to the wrong positive???

 

[cobolt]

Middle post on top of contactor should be battery positive you've connected. Where have you taken the negative for the remote from?

 

[davethedog]

Thanks and the negative was one I found in the area, what should I have done?

 

[cobolt]

Should go to the middle spade terminal of the contactor I think, again sorry I can't see so well on my phone...but that should be -ve and also wired to negative terminal of the motor.

The strange thing is that wherever you have connected the positive to, the solenoid will either close and the windlass will operate, or the solenoid won't close and nothing will happen. I'm struggling to see how your wiring on the low current circuit, which must either be 12V or 0V, ( 0V if wrongly connected), could ever reduce the current on the high current circuit.

Is it slow in both directions with the wireless and fast in both directions with the foot switch?

Positive for the remote is on the correct terminal.

The white wire from the remote is connected to the blue wire from a foot switch just before it connects to the contactor, which is correct.

The yellow looks to be connected to a brown wire and it looks like the black wire is also connected to a brown wire. Hard to see for sure.

There are three spade connections at the contactor, one will be negative, the black wire goes here. The white and yellow go to the other two terminals.

You can cut the spades off and crimp new ones on, with an original wire and a wire from the remote relay in each spade.

Or, you can cut each wire and put a butt connector in.

Either way would be much better than the Scotchloks, they are going to bite you in the bum one day :ambivalence:

I agree with your logic Richard. The only thing i can think of is that something is amiss with the connections and the contactor is chattering rapidly.

Indeed Paul. I did suggest the chattering in #2, and that's still my only theory, but I think that the noise would be so obvious that Dave couldn't miss it.

Thanks once more all and will look at the negative connection as that surely can be the only problem then!

Update, sat here in Newtown creek and whilst enjoying the glorious weather had another look and swapped the negative to the wireless receiver unit to the centre of the contactor as advised.... All works perfectly and very many thanks for the help.

That's good to hear but ...

Can the experts explain why that misplaced negative made the windlass run slow? It makes no sense to me.

Very good, glad it's sorted.

So am I happy and very many thanks to all!
