I want to do a compression test on my 12a (85 GS) and was wondering what wire/wires and where they are to shut off the fuel pump.
Thanks!

Pull the fuse:P its located under da dash, DS. should be a 15 amp (red one) in a verticle pos.

 

nevermind, found it

 

20amp labled 'engine'

 

lol there ya go... my bad.. sorry but ya got it figured. (Y)

 

thanks zd!

 

theres also a nother.....laymans way of doing compression test, just take out the trailing plugs, crank it.....you should hear three equal puffs from each rotor.

If you here 2 puffs i think it means a side seal is gone, and only one puff an apex... i dont remember how it works but if ya dont here the three.. somethings wrong lol
