If you measure <1 Ohm, most likely the diode is burned. This happens more often if you wait till the contact-points are completely gone...

The diode is not needed for my kit, but if it is short-circuit, the pump won't work.
Most likely also your FP-Fuse in the bike is burned if the diode is shorted: surely the short-circuit current was supplied by the bike in some stage...
try another pump...
Cheers....will do. Thanks for your help. I'll see if I can get it completely apart tomorrow.
