I use wd as a grease/grime remover, but you definitely have to be careful were you spray it.
As far as electrical connections go wd is great at expelling water and has no problem conducting electricity.
I believe I have a faulty component which wd won't really help with.
I got a knockoff startswitch/headlight assembly for 9.9 euros, hope this is the fix.
Thanks to AXY i have a manual and will be disassembling the steering colom this weekend to replace
