test mpem

[seadooer]

How do you test the mpem with a multimeter to see if it is still good? lots of water and corrosion in the fuse box. Fuses don't look blown but everything is a mess. Need to dry everything out and start from scratch. Want to see if mpem is still good or needs replacing. thanks

Here is a list of results you should get from testing your mpem on the 717cc rotax. Make sure you have all the wires completely disconnected or damage to your meter can occur.

METER + ...........................METER - ................................Value

RED........................................RED.... ....................................< 1 OHM
(ring terminal)......................(female terminal)

RED....................................RED/PURPLE.................................< 1 OHM
(ring terminal)......................(female terminal)

RED.......................................BLACK... ...................................> 20K OHM
(ring terminal)......................(ring terminal)

BLACK/RED..............................BLACK............ .........................> 10K OHM
........................................(ring terminal)

WHITE/GREY............................BLACK............. ....................... >100K OHM
........................................(ring terminal)

TAN/BLACK..............................BLACK.......... ...........................>200K OHM
........................................(ring terminal)
