Guys,

Continuing with my long-winded diagnosis of the no-spark issue...

I've received an OVP relay from an online scrappy, but it looks completely different from the one I have...it's about half the length, and has two fuses on top, instead of one. It was supposed to have come from a 300CE.

Part number is 201 540 37 45.

How can I tell if it's ok to use?

In the early days just one was used, next a second type came out with more outputs, only the later one is supplied these days, its just that all of the outputs are not used. It should be fine
