It's finally time to begin reassembly of my 66 BJ8. What I think to be the overdrive relay, just to the right of the overdrive throttle switch (looking aft), is in pretty good shape, was working at disassembly. It cleans up well, but I'm concerned about its working condition. Is there a way to bench test this relay? ID on the relay is "Lucas 6RA 33213E 12V 3 66" The four spades on the bottom are labeled C1, C2, W1 and W2. Thanks.
