Dyna/S Installation / Troubleshooting on the Honda GL1000

Setting up a Dyna/S ignition on a GL1000 can be a vexing proposition.  The good news is that done properly – it’s a “once and done” proposition!

Dyna/S: How to Time / Adjust:

Dyna/S Installation on the Honda GL1000:

Note: There is a “fixed” plate and an adjustable plate.  Dyna’s instructions are rather poor, but the “fixed” plate is actually adjustable as well (on the back). 

If the “fixed” is not adjusted near the center of its slot, you will run out of range on the other plate.

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
  • 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 in 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: http://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)

  1. McGuire says:

    I have dyna coil and ignition system bypassed ballast and condenser. and I have 12v at the red wire but I don’t get a light between the coil wire and ground when I try to time it. the key is on and I have triple checked all wiring. I have also tried to manually trigger the ignition with a magnet and still no light and i cant find anyone else having the same problem. I also tried to start it and I just got gnarly flames. Don’t know what to do or where to go from here.

    Just in the interest of detail, the Dyna S Installation Instructions identify the “fixed” and “adjustable” pickup components on the Dyna S “plate”, as “modules”.

    • My view: Dyna’s instructions are very weak. The unit has pickup modules mounted to 2 plates …both plates are actually adjustable. Randakk

  3. I found out that i had to adjust the so called “fixed plate” in order to dorrectly perform the split timing procedure. I also had to remove the spark advance weights to remove the OEM points cam, and then reinstall the weights.

    • Howard: Correct. As I mention above: “the “fixed” plate is actually adjustable as well (on the back).” This detail trips up a lot of people! Rndakk

    Make sure to get the locking screws tight, had an issue with the one I had on my 77, the screws loosened up enough to allow the timing to change.
