My '73 1.7 is getting the FI system re-installed after the PO put carbs in.
I'm not getting power to my fuel pump--I've tested continuity and think my problem lies in the relay board. The left post for the 25A fuse should receive 12V and I'm getting nothing. The post looks a little melted like something happened to it at one point. The rivet from underneath (red, 2nd picture) is continuous, but this should extend onto the tract (not sure the correct terminology), right? There seems to be a break between the rivet and the tract (green). Sorry about the lack of focus... If so, how do I make a quick fix? Thanks! Attached image(s)

Yes, clean the contact and rivet really good. Wire brush carefully until it shines, them wash with alcohol. Let dry and solder. Be careful with the heat level, you are working around plastic. Did mine years ago and no problems. If after soldering, you don't have continuity, the the problem is on the back side. You will have to remove the sealant then clean as on front side and solder. Should be good as new- maybe better. There are some threads about resealing the back side also, just have to search for them.
