Hi folks
have been reading lots of posts and suspect either my OVP or Klima relay are suspect. I have no test equip other than a couple of multimeters.

I checked out the replacement prices and they are not cheap so can anyone tell me how to test these relays with just my multimeter and pieces of wire?

I will need exact pin numbers please if possible.

the symptoms are no cold air, condenser completely cold. I have been able to spark the compressor into life at idle by pulling and replacing the contact on top of the accumulator so I dont think thats the problem. My feeling is the condenser is being tripped out by one of these two relays.

all help of reference to posts I have not yet found appreciated.
thanks
Keith
