Hi CBR Forum CBR 1000f (1992 – N-model).

Basicly all electrical components are functioning but as a result of repeated start failures over time (& enginestops while driving) I got aware of the consequence of voltage drop. For a start I had 12,71 V at the battery (brand new), 11,20 V in the wiring & 10,45 V at the ignition coils. I have found & repaired quite of lot of minor problems, cleaned & sanded all connectors & replaced some connectors. In spite of this...status is (when all electrical component are cut off except the fan) a current of 12,71 V at battery & 12,08 V in the wiring & 11,46 V at the ignition coils.

When I separate the wiring in the big red connector leading from the rectifier to the alternator I get 12,71 V on the battery and the same value in all the wiring incl. the ignition coil. But there are 0,60 V in the white wire (ground). Aha I thought - a shortcut in the connector between the black wire (leading current from the fuse box to the alternator) & the white wire (ground from alternator to rectifier). I do not have immediate access to new connectors of that type, so I made a new separate connection for the the black & white wire – & I expected full current in all the wiring but no, no no. The samme resultat as above. Battery 12,71 V 12,08 V in the wiring & 11,46 V at the ignition coils AND 0,60 V in the white wire (which generally fits the lack of 0,60 V in the wiring).

I have earlier made measurements on the alternator - & the measures fit the values in the Honda Service Manual. I have replaced the rectifier and rectifier ground is sandet & look fine. I am confused & in a dead end.
Hope?
