TK Ts-200 cutting out

[shaun220]

Hey all, I have a Thermo King TS 200 that is cutting out code 63 intermittently,(might run for 3 days no problem) I have changed fuel filters, cleaned pump filter, changed fuel solenoid. Wondering now should I look at a the board k9 & k4 (pull and hold) or microp. Any known issues?
Thanks

The switch on the outside of the unit can give issues that's the on/off switch.

Check your RPM sensor as well.
Interface boards on these units are bad for corrosion.
Have you been able to catch it shutting down? It would be helpful to know if it's fuel related or electrical.

Bridge out Hp switch had one customer with same fault dropping out fuel solenoid

[cadwaladr]

Do not ever bridge out hp,unless your monitoring the unit with gauges attached !

Bridge out he switch only if u want to blow it up that's a defo no no ,usual suspects cad and irm have said obviously like me spent many a hr on a tk only other common issue is fuel gauze and sometimes weak solenoids just be patient and sit with it great job like this to catch up on paperwork nail it and the next one is easier
