100A terminal stud ?

100A terminal stud / windlass wiring questions ?

Hi,

The +12V lead from the battery to my Lofrans windlass runs from the battery to the solenoid, but there is no such connection for the -ve lead. It would be quite inconvenient to run the -ve lead directly to the motor so I am looking for something to act as a staging post. Does anyone know where I can get an M8 terminal stud capable of carrying 100A or so ? A water resistant / short proof cover would be nice...

While I am here, the solenoid has connections for direction switches with the +ve common between the switches being connected to the battery +ve and the -ve solenoid input to the battery -ve. The Lofrans diagram (see fig attached) shows the common +ve connection for the switches going back to the battery switch (before the cct breaker), but can it just be connected to the +ve supply input to the solenoid (after the cct breaker) or will that not work ? Can the -ve be conected to the stud terminal or must it also go back to the battery ?

Thanks,

Boo2

Merlin www.power-store.com do them Don't think they do covers for the 8mm. Nothing unusual about the studs and you should be able to get them from a chandler.

BTW there is a note in the catalogue "There is no maximum current rating for studs as current is transmitted through the ring terminal stack"

Thanks for that, do you (or anyone) have an opinoin as to whether or not the switches supply needs to go back all the way to the battery or can it be taken locally at the solenoid box ?

Thanks again,

There is no reason whatsoever why you cannot take the positive for the control switches from the positive at the relay, so long as the fuse is connected in-line with the control switches.

Pas the control is after the main fuse/breaker does not matter, as the windlass would not work if the main switch was off, no matter wher you took the control positive from.

As a matter of interest, the control positive for my bow thruster comes from the bow thruster itself.
