What relays to use for Head light relays

[Ned Ritchie]

I like my things bigger, faster, and brighter.

Therefore I like to use the Bosch 70 amp relay for the headlights.
Usually there is one such relay plugged into a harness under the
steering wheel of every older turbo Audi.

I've burned out several 40 amp relays in the past and the 70 amp has
more conductance, Mhos, across the contacts.

Hey! . . . "traipsing though a bone yard" is a serious hobby for some of
us.
It happens to also be the one place that wives will not follow you to. A
"boneyard" is a place of repose and contemplation . . . and miracles.
Those
relays just jump into your pockets . .all by themselves . . . aint that
sumthin!

Do you have a source for these Bosch relay kits? I like the idea of a
prewired relay socket. I could have used one of these when I was
figuring
out how the AutoCheck system worked.
Maybe someone on the list has a source for a "male" lamp socket
connector
that would plug into the existing harness lamp connector.

Regarding longevity of relays . . . I would think that a used Bosch
relay
would outlive a $3.00 Radio Shack relay. The relays that jump into my
pockets are from relatively late model cars.
Come to think of it, other than the fool pump relay, I have not read of
any
relay failures in the posts.

As I mentioned in another post, the double contact design of the Bosch
relay
is ingenious. The second set of contacts was perfectly clean in the
relays
that I examined. And I always examine the relays before using them.

Well, its time to pack the picnic lunch for my therapeutic visit to the
"boneyard" . . . adios.
