Theres a few members who have had problems with their 275-206 relay, which is what B&M recommends. This relay will most likely burn out because there is a thin white wire that is triggered to pass a 12 volt current from the ignition switch to the relay, and down to the starter. The white wire is so thin that it will burn out because of the amount of current flowing through it. Its very similar to a fusible link. The pictures below will show you my relay that burnt out 2x's. The first time I re-soldered another white wire in place. But it burnt out too. So I then re-soldered another thicker gauge wire. Be advised that you must have a soldering iron that is capable of producing heat at least 350-400* F. Today I tested the relay and it never got hot at all. So I say mission accomplished. if you have any questions, let me know and I will help you out or explain what I did to make this junk relay work.

Below is a timeline of events of my progress to the successful solution to the relay.





Replaced wire burnt out again.

Forgive me if I am misunderstanding this,
But the whole point of a relay is to relieve the "comfort" switch of a high current load. You could flip a switch that would handle the current draw but who wants to flip a breaker sized switch?
That being said, who would design the main (power bearing) circuit of a relay with a wire inline only capable of handling minimal loads? Especially in a starter circuit?
Are you sure its not hooked up wrong?

Like I said in the header. B&M recommends, not provides, recommends that said relay, which is from RadioShack. Some cars for some reason won't burn up the white wire. There are many members who have experienced this issue and simply do without the relay. Yes it is hooked up properly too. I don't know why B&M recommends a relay that has terminals that can handle a messily 3-5 amps while the starter can see 25+ amps. This thread just covers a little bit of my experience. Check my profile and look at some of my recent threads. You will find that I burned up the original white wire and the resoldered new wire too.

The starter its self will draw close to 200A.
3A to contact the solenoid doesn't leave any wiggle room.

What are all the prongs for on the relay? Why so many?

The starter draws 25 - 35 amps, not 200A.

According to the Radioshack packaging, the relay has a 5A rating for the prongs.
There are so many prongs on the relay because, well, its a relay.

Ok. The wire in focus draws 25-35 amps (solenoid). I'm not worried about the starter current draw.
