I have been having some problem with my new
to me KAD43...replaced frozen alternator and
tach by a Volvo Tech...their found that there's
a break somewhere...he was able to jump the
alternator somehow and got it to charge, and
also the tach working...mechanic mention it's
best to install a new line...shop owner want
to trace the break and fix it...all Greek to
me, but when the owner want $110/hr and think
it will take 8-10 hours to diagnose and fix, I
took the boat home...Does anyone know what the
problem could be? |

Alternator is energized thru light on alarm panel by light brown wire that attaches to D+/61 terminal on back of alternator. It also has a resistor under black box cover that allows low speed alternator energizing. This only applies to Volvo alternator. If aftermarket installed, all bets are off. |

Thanks Dick...would you happen to know how I can
test if the light on alarm panel is sending signal to D+ terminal. |

Hi Dick,
Would the resistor be part# 873717?
Please let me know if when you have
a minute...Thanks. |

Man, this alternator thing is getting very
upsetting...my local Volvo tech can't fix it
nor can my dependable mobile marine tech.
I had the alternator regulator replaced because
it does not work at low RPM...new regulator seems
to take care of the problem when I have it at home on the hose...rpm reading 600...but when I
am in the water...rpm reads about 550 and the
damn thing cut-out again and I get the battery
alarm going off...when I rev it pass 600RPM she starts charging...
Maybe, just maybe I need to increase my idle to 600RPM? Does anyone know what is the recommend idle RPM for a KAD43 and how do I adjust it? |

If you are starting from tuna tower or flybridge, the resister that I spoke about before must be in use or you will get what you describe happening. It is under black plastic box. Can't miss it. check it out. |

Thank you for responding again Dick...I really
appreciated it.
I did find the resistor in the black box. It is
a 33 ohm resistor that is wrapped in heatshrink
tubing. it is splice on to the brown wire and goes to the relay for the compressor. It ohm out
correct so it is still good.
After reading your notes again...you said "under" the black box, while the resistor I found is "in"...Am I missing your point?
the black box... |
