Plug Polarity Poll -- SAE 2-conductor plugs
I have been using SAE plugs for quite a while for basic wiring on different bikes. Even my accessory boxes that have Powerlet or co-ax (heated gear) outlets will connect to the battery with an SAE plug so I can connect different boxes or accessories on different bikes. My heated jacket, likewise, came with three options for the power cord and they all connect to an SAE outlet inside the jacket pocket.
I always wire my SAE plug so that if it is not in use and it flops against the frame, the naked contact is ground anyway -- no short.
I just got an electric pump with an SAE plug on the pump and 2 SAE plugs to connect to power: clips and cig plug. Both put the battery positive on the naked contact.
I thought this was to match Battery Tender but I was wrong. My poll, above, is wrong to mention Battery Tender. It's the Stop N Go air pump that is wrong although other devices may be also.
So what's your preference?
