Original X wiring

Hi me again
Just been to test my existing X panel and a couple of question popped into me head

1/ Running lights why do I have 3 wires going out from the switch ?

2/ The negatives coming from the lights etc all go together onto a bolt through the plastic bodywork rather than to the negative of the switch

Any ideas ?

I can only offer a bit of

I can only offer a bit of info. The boat has 3 lights, stern ,mast and stem.., so that is probably the reason for three wires. I imagine they should have a common negative.

Hi David

Hi David
Our mast light is on a different switch, unless it is covered by the running lights as well
so
running lights = bow, mast & stern
mast light = mast only

By the way, the standard

By the way, the standard macgregor wiring bring all negatives back to a bolt that is secure through the liner as you say. That is then taken to the negative terminal on the fuseboard. Positives will go to various devices but basic supply would be one circuit for running lights at bow and stern plus one for mast steaming light. If additional lights were placed on the mast then there could be a 3 pin connector on the deck rather than standard 2 pin. Interior lights also on one switched circuit. I found the nut on the bolt very hard to access and tighten properly so I fitted a proper negative bus with each one secured properly . My fuse board takes all the upper deck stuff while for floor level stuff like sockets and pumps etc these go to a master switch near the steps and have individual in line fuses.

Hope that's helpful.

My M also has the three

My M also has the three cables and three switches, however

Running lights - bow

Mast - forward facing mast white light

Stern - rear facing white light

Switched this way so that you can differentiate :

Sailing - Running lights and Stern

Under power or power and sail all three

At Anchor Mast and Stern

Hi all thanks for the help

Hi all thanks for the help

Roly I forgot I'd removed the lead from the bolt to the switch board, so all good now.

Jonathan, I'm going to test the lights again tonight but I think your right, in that the mast is onto the running lights and on its own switch, but I'll know for definite once it gets dark

Thanks again

If you want to put additional

If you want to put additional tricolor at mast top or a deck illuminator then there is a way of reversing the current and placing blocking diodes in the circuit. I read about it as did it a couple of years ago quite successfully. ....didn't have to thread extra wire around my boat .
