plugs

[X-ray]

I've been introducing myself continuity testing with my less than desirable(POS) harbor freight multimeter.  My left cylinder isn't firing and I believe it may be a black plug on the left of the bike that has seen better days. I've tried to spray electric contact cleaner and use a little file but no luck. Is it possible to remove the spade connectors from the plastic plug? I've been trying to jam a piece of sand paper in the end but can't make that work either.


Btw I already checked the auxiliary ground plug, it's in good shape.

Well I figured out the female side but to my dismay I think I'm going to remove the plug all together and replace with individual connectors. Should I be getting a certain grade of connector or will harbor freight grade with hear shrink tubing be up to the task? What gauge wire is it I'm fiddling with?

If you mean a connector plug (not a spark plug) .. probably doesn't matter heaps. ..BUT .. I checked the heat tolerance of the ones I replaced (on the packaging) before I bought them, it does get very warm down near the motor area. .. and I replaced plugs because wires/old connector were heat damaged

Is the plug sparking?  Is it wet?

I ask because my left cylinder wasn't firing, and it turned out to be a leaking petcock diaphragm which was causing the engine to suck in fuel and drown the plug.  As soon as we removed and capped the vaccuum line from the carb, it fired right up on both cylinders.

So if you've got spark, maybe pull the petcock vaccuum line and check for fuel.

It's not a spark plug. It's one of the plugs in the loom on the left that resides under the plastic body panel. Thanks though.
We I first read your suggestion I was thinking you were leaking fuel on your electrics!   
I wasn't thinking spark plugs at the time.

Are these wired 14 or 16 gauge? Some replacement connectors I have have a range of acceptable sizes. After stripping the ends I'm pretty sure it's one of these two but the connectors switch wire sizes right at the 14 and 16.
