frequency limiting output that is
less then the coil requirement.
- Connect leadwires to power
source. Verify voltage rating*
per nametag on coil.
- Keep wiring away from pinch
points and moving components.

Note:
Stabilizer clips should never be located over the set
screws of the hub.
Single disc brakes always use two stabilizer clips, locate at 90°
from each other.
Double disc brakes typically will not require stabilizer clips, how-
ever there are some special modifications that will use them.
Rev A & B
may have these clips may have these clips located
1 per disc, and should never be positioned in line with each
other.
Rev C
will have only one clip, used on the inner-most disc. No
clip will be used on the outer-most disc.
Three disc brakes will never use stabilizer clips on friction discs.
Note
: Friction discs can wear to 1/2 their original thicknes, or .093”
