[DMCForum] Re: Headlight switch



What you say rings true. I hear the relays click in behind me when I
turn the lights on. I don't doubt what you're saying but how do the
contacts in a sealed relay get dirty?

The headlight switch isn't sealed. Although it doesn't power the
lights, wouldn't that kind of crud -anywhere- in the circuit cause a
heat build up at the weakest point?

Also, if what you say is true, do you recommend that I replace my
relays? I don't know how old they are.

Thanks,

Rich A.
