Testing plugs
Recently fitted a new plenum to my car. Thanks for Dogsbe for supplying it, he was excellent, thoroughly recommend him.
What I would like to do though is also check that the VIS plugs are working correctly (the plugs you connect to the 2 VIS motors). If anyone has any ideas of how this might be accomplished I'm all ears 
Thanks.

KevG has some device that he made for testing the VIS valves... Not sure if that'd work.
edit:
Here's the link - http://www.themg.org/vb/showthread.p...ghlight=tester

Kev's bit of kit tests the motors (brilliantly btw ). What I'd like to do is test the plugs that connect to the motors.

Wonder if making a vis indicator work? Would tell you when the valves are open and if you know the motors work and the indicator doesnt flash up can assume an electrical fault at the plug.

Sounds like the kit fitted to the dash.

Yer thats what I ment Prehaps if it doesnt light, will signal a fault with the plugs. Guess depends where the VIS indicator taps into the circuit, Ive got one but never looked at the wiring of it.

Led's always illuminated (green) when in closed state, when cam moves green led extinguishes and changes to amber and then vice-versa to show the cams have moved off and rotated to the second position and made contact. So it is really only telling you that the micro-switch has seen the actuation and made contact. Nothing to say the plug is okay, otherwise it'll need a secondary circuit to show there is power there etc, is it worth it when the fault is always the vis unit? I think the vis indicators is enough on its own to show that the cam has actuated in both positions which tells you the switch is working in both conditions.

I was just thinking out loud really, Suppose a circuit to test current in the plug would work as Nor wants to test the plug itself. Kev is the one to ask.
