- Both modules have to be timed spot on!
Dyna/S Installation on the Honda GL1000:
- Ditch the OEM condensor! Not required with electronic ignition.
- Ballast is retained, “piggy-backed”or eliminated depending on the coils used and the vintage of the Dyna unit being installed. More on ballasts here: See: https://www.randakksblog.com/?p=1420

Dyna/S Common Problems:
1. Total loss of ignition – suspect the fuse that feeds the Dyna unit….typically this is the turn signal circuit if the Dyna install instructions were followed. Dyna supplies a Scotch-lok connector to tap into the turn signal circuit. Those connectors are not very reliable.
- The ignition switch and kill switch are possibilities, but not if power is reaching the Dyna unit continuously
- Depending on the whim of the original installer, you may or may not have an “extra” fuse protecting the Dyna/S unit hidden somewhere in the power feed.
- Failed 30-amp master fuse
- Main battery ground cable connection issue
- Main battery positive cable connection issue (battery to starter relay)
- Main harness connector (above battery)
- Partial battery failure
- You may or not have a ballast resistor (depending on various details). You may in fact have 2 ballasts resistors depending on the details. You may or not actually need a ballast resistor if you have a Dyna/S installation. In any case, if you have a ballast and it fails – you will lose ignition (at least when the starter button is released). More details on ballasts here: https://www.randakksblog.com/?p=1420
2. Partial loss of ignition – (Losing only #1/#2 or #3/#4 ignition.)
- Suspect bad wiring or a short to the Dyna unit from one of the coil primary wires (a “pinched” coil primary wire near the air filter housing is common).
- There is a set of connectors at the mid-point of the coil primary wires (near the battery) that sometime come loose and must be checked.
- Failed Dyna module (see Dyna Module testing procedure)
3. Module Reversal – ( “F” marks way off from where you expect them)
- Suspect reversed wires at the mid-point of the coil primary wires (near the battery)
Dyna Module Testing Procedure:
- The only solution for a failed module is replacement.
