Discussion:
Code 23

Hi All,
I was hoping someone could point me in the right direction.
Truck was hard faulting Code 23. I checked battery condition. OK.
No shorts to chassis. Motor tested out ok. Isolated motor cables and tested no shorts found. Q1 tested good on diode test. Rec1 tested good. Checked insulator at Heatsink. Ok. Checked all fuses. Ok. Contactors ok. Performed test A01 and got a steady 6 volts. Couldn't figure out where the connector was for test A10. Was kind of spinning my wheels and made a few calls and it was recommended to me to try a Powercard. Customer had a known good one(my instinct said this could go bad). Installed it and now truck doesn't power up. Installed old card and same thing. Checked wiring schematic and was wondering if the F1 fuse on the filter assembly was like the filter on the Reachs? I've had the fuse pop on the Reach's and they won't power up. If it does the same job would anyone know where if would be located? Of course this happened on a Friday afternoon(Murphy's Law) LOL.
Any help would be greatly appreciated.
Thank you,
Jay

Code 23 is always a Q1 transistor failure

Fact of the week
In 1923, French tennis player René Lacoste was promised a crocodile leather suitcase by his captain if he won his next match. He lost the match but won the nickname "the crocodile" which he had sown onto his tennis attire. Ten years later he launched the first polo shirt and Lacoste, the first brand to feature a logo on its clothing.
