Another couple of thoughts!

1. Checking voltage at the fuse terminals will not tell very much as this is on the 'live' side of the relay.

2. To bypass the relay bridge the 30, 87l and both 87e terminals. Beware, the ingition switch may not shut off the engine if you do this. You could use the 15 instead of the 30 but this may overload the ignition switch.
