Re: Carrier Supra 750 wont run reefer says oil warning
1. was the unit only cranks and not running? if so, it will alarm on "low engine oil pressure" as it sends signal to micro-p. try to check first the cause of not running by checking the fuel system; fuel sol. & diesel pump electric feeds.
2. if it is not cranking at all then check the oil sender or better try to cross its connector before re-starting.

Re: Carrier Supra 750 wont run reefer says oil warning
If it alarms oil before running it is the alternator. The micro sees voltage at the alternator and thinks it's running. Therefore it sees no oil pressure and alarms.
