HOLD ON... try this test....<br /><br />MERCURY BATTERY-POWERED CDI SWITCHBOX TEST<br />FOR DISTRIBUTOR MODELS<br /><br /><br />This test is for the 332-2986 switchbox used from 1967-1978 on all the<br />inlines.<br /><br />This test assumes your coil is good (most all are).<br /><br />DISCONNECT BATTERY<br /><br />1. Turn off ignion<br />2. Disconnect all 3 wires on the distributor side of the switchbox.<br />3. Remove the HV lead from the coil to the center cap (remember it unscrews<br />from cap)<br />4. Reconnect that HV center lead to the COIL side only.<br />5. Position that HV lead about about 3/8" from ground (block, shrouds etc)<br />and find a way to hold it there.<br />6. Jumper the brown and white terminals on the dist. side of the switchbox<br />together.<br /><br />RECONNECT BATTERRY<br /><br />7. Check that you have +12 V at red terminal.<br />8. Turn on ignition and verify +12V at white terminal (on red terminal side)<br />9. Touch the black terminal to ground - unit should cause spark each time<br />you touch ground.<br /><br />If that passes and it won't fire at all, suspect the trigger.
