8.14 TRoUblESHooTINg - HEART RATE ISSUES - CoNTINUEd
CHAPTER 8: TRoUblESHooTINg
- Remove the console and perform a continuity test on the wiring going from the handlebar connection frame to the console. With a
multi-meter set for ohms, place one prong on the HR grip wiring coming out of the console mast (Figure K) and one prong on the wiring that
connects to the handlebar wiring (Figure L - match red with red and white with white). An ohm reading of less than 1 should be expected. If this
reading is higher than 1 or if there is not a reading, replace this section of HR grip wiring.
b. If your problem is not with the HR grips, a continuity check should be performed on the unit to verify that the console is properly grounded
(see Service Bulletin – Continuity Test on Matrix Climb Mills).
- Once the console grounding has been verified, the heart rate board ground wire should be verified.
- Remove the 6 screws holding the console back to the front (Figure M).
- Check to make sure that the HR board ground wire is plugged into the console ground wire that plugs into the ground wire run down the
console mast. Retest for HR if not properly connected.
- Remove the 2 screws holding the HR board to the console frame.
- With your multi-meter set for ohms, place one prong of your multi meter on the ground wire coming from the HR board (Figure N) and
the other on the console ground wire that comes out of the console and plugs into the ground wire going down the console mast. An ohm
reading of less than 1 should be expected. If this is higher than 1 or if there is not a reading, replace the HR board ground wire.
- If no problems were found using the troubleshooting above, replace the HR board.
- If the HR board does not solve the issue, replace the console.

8.15 TRoUblESHooTINg - TogglE ISSUES
TogglE ISSUES
1) SyMPToM:
a. No response on the grip toggles
b. The console beeps when the toggles are pressed, but no change on console.
2) SolUTIoN:
a. Remove the screws holding the 2 halves of the HR grip together (Figure A).
- Check the connection of the toggle wiring to the toggle keypad (Figure B).
NOTE:
There should be a red dot on both the toggle
harness and the grip wiring indicating the correct way to plug in the toggles (the red dots should be on the same side of the connector).
- Place a screwdriver or other metal object between pins 1 & 2 and 2 & 3 on the grip wiring (Figure C). The console should beep when
these wires are bridged. If the console beeps, replace the toggles. If the console does not beep, continue with the steps below.
- Loosen the 6 handlebar screws on each side of the unit (Figure D).
