Mikuna dieselvarmer resetting?

[ollebolle2]

Strømmen ble tatt når varmeren gikk. Etterpå lyser det i malfunction dioden og varmeren starter ikke.

Noen som vet hvordan denne skal resettes el videre feilsøking?

Kontroller hvilke av de to sikringer som er utløst og 0-still denne. Sikringene er plassert

henholdsvis under skyvedekslet oppe på varmeren og i utløpet til varmluften.

ON/OFF Frequency Indicates:

1 : IGNITION FAILURE

 

2 : NO FLAME SENSING

 

5 : MOTOR FAILURE

 

7 : FUEL PUMP FAILURE

 

8 : GLOW PLUG FAILURE

 

9 : BATTERY VOLTAGE ABNORMAL or OVERHEATING

 

 

 

IF THE HEATER FAILS TO START BUT THE DIAGNOSTIC IS NOT FLASHING-CHECK THE THERMOSTAT BY LINKING THE TWO RED WIRES TOGETHER. ON INTIAL OPERATION OR IF THE VEHICLE HAS RUN OUT OF FUEL THE SYSTEM WILL NEED TO BE RE-PRIMED. THIS SHOULD BE DONE BY PUSHING FUEL THROUGH THE PUMP WITH A SYRINGE OR BY USING THE MIKUNI SP21 PRIMING PUMP.

 

IF THE GLOW PLUG FAILS, INSPECT THE BOSS FOR CARBON DEPOSIT OR STRAY STRANDS OF S/S GAUZE. CLEAN AS NECESSARY AND ENSURE THAT THE GAUZE IS NOT BURNT OR DAMAGED. IF IT IS REPLACE THE GLOW PLUG BOSS ASSY.

 

1. Ignition Failure

CHECK FUEL SUPPLY > FROZEN FUEL LINE? > CHECK AND CLEAN FILTER IN FUEL PUMP > CHECK FOR BLOCKED STANDPIPE > COMBUSTION AIR OR EXHAUST PIPE BLOCKED OR DAMAGED? > IF HEATER RUNS OK FOR APPROX 3 MINS AND STOPS-SUSPECT FLAME SENSOR > IF HEATER SMOKES BADLY AND STOPS AFTER 3 MINS STRIP DOWN AND DECOKE.

 

2. Flame Sensing

CHECK ALL PLUGS AND SOCKETS IN WIRING LOOM > LOOK AT FLAME SENSOR;IF THE SEALANT IS PUSHING OUT OF THE RETAINING NUT REPLACE WITH A NEW FLAME SENSOR.IF NOT CHECK FOR BAD CONNECTIONS ON PCB INSIDE GLOW PLUG COVER > CHECK CONTROL BOX.

 

5. Motor Failure

CHECK MOTOR FUSE 12V=7.5A 24V=5A > IF FAILED ENSURE THAT MOTOR SPINS FREELY > CHECK WIRING LOOM CONTINUITY > CHECK MOTOR > CHECK CONTROL BOX > CHECK FOR BAD CONNECTION ON PCB INSIDE GLOW PLUG COVER.

 

6. FUEL PUMP FAILURE

CHECK CONTROL BOX > CHECK CONTINUITY OF WIRING LOOM AND INSPECT FUEL PUMP TERMINALS FOR CORROSION > CHECK CONTINUITY OF FUEL PUMP.

 

7. Glow Plug Failure

CHECK GLOW PLUG FUSE=25A (IF APPLICABLE) > CHECK GLOW PLUG AND GLOW PLUG RESISTOR ON 24V MODELS. > CHECK CONTROL BOX > CHECK WIRING LOOM. NOTE:THE GLOW PLUG RESISTOR IS A DIFFERENT PART TO THE GLOW PLUG -DO NOT INTERCHANGE! [24 VOLT ONLY].

 

8. Battery Voltage Abnormal

THE HEATER WILL CUT OFF IF THE BATTERY VOLTAGE IS TO HIGH OR TO LOW. OPERATING RANGE FOR THE 12V MODEL IS 10.5 > 14VOLTS AND THE 24V MODEL IS 21 > 28 VOLTS. CHECK THE VOLTAGE AT THE HEATER WHILE IT IS RUNNING (SO THAT THE BATTERY IS UNDER LOAD) WITH THE BOAT ENGINE OFF AND AGAIN WITH THE ENGINE RUNNING TO ENSURE THAT THE VOLTAGE IS WITHIN THE OPERATING RANGE OF THE HEATER.

 

9. Overheating

MAKE SURE THAT THE HEATER HAS COOLED DOWN AND CHECK THE MOTOR FUSE > CHECK THE AIR INLET AND THE HOT AIR OUTLET FOR BLOCKAGE THE HOT AIR OUTLET FOR BLOCKAGE OR RESTRICTION. NOTE: OVERHEAT CUT-OUT WILL AUTOMATICALLY RE-SET WHEN THE HEATER COOLS DOWN.
