What's the best way to clean electric box connections. All me lights and that are working but the electric start is playing up! Bit of white corrosion on the contacts. Used wd-40 on everything but had no joy. What's good to clean them with? Was thinking vinager and sand paper??
Lemon juice (Citric acid) to clean off the corrosion, followed by a quick rinse off with water then Isopropyl alcohol to dry them off. Check the brake lever switches, as you usually have to pull the brake in to activate the relay, before the starter will turn over on the button - they can work loose and fall out and they may just need pushing back in. A dead giveaway of this is that the back brake light will be playing up too, if it's the switches.
All the brake lights and front lights and that are fine mate. Will clean all the connectors tomorrow and post results. Cheers merlin
