1982 GS650 E
Voltage at the battery 12.35
Voltage at the fuse panel 12.10
Voltage at the coils with all wires connected; 9.6
Measured this voltage at the orange/white connector blade.
When I DISCONNECT the Black/yellow wire from the right coil the voltage jumps up to about 12
With that wired connected and the white wire disconnected from the left coil the voltage stays at 9.6
(In other words; there is good voltage at the coil when the black/Y wire is disconnected from the right coil but there is a drop when it's connected properly. The white wire on the left coil has no affect on voltage whether connected or not)
I wired in a different coil and got the same result: significant voltage drop when the right coil is connected.
With the old coils connected I wired in a different igniter box. Same result; good voltage when the black/yellow wire is not connected but a significant (1.5 to 2 volts) drop when the black/yellow wire is connected.
Removing the signal generator had no affect. The voltage drop is still there even if the SG is not connected at all.
As a last resort I pulled the black/yellow wire out of the harness looking for a cut or something where it might be shorting out. Nothing...just one straight, clean wire from the igniter connector to the coil plug.
Any ideas?
And, yes, this is having a significant impact on starting. There isn't enough voltage for ignition when the starter button is pressed. The starter engages but there is not enough spark to ignite.
