Amplifier Module Test

  1. Disconnect distributor harness connector from amplifier module "W" and "G" terminals. Disconnect the high tension lead from distributor cap. Turn ignition on.
  2. Hold high tension lead with a pair of electrician's pliers and position it 1/4" from good engine ground. The ground should be as far from the coil and amplifier module assembly as possible.
  3. Use a jumper wire to feed terminal "G" of amplifier module with successive impulses from battery positive terminal. At each impulse, a spark should jump the gap to ground. If not, repeat same test with a new amplifier module. If spark now jumps gap, install new module.
