Gents,
I could use some help figuring out an electrical issue that has reared its ugly head as of late. I would be just guessing where to turn at this point. Here is the skinny.
2008 Heritage with 20K miles, PCV, Stage One Air Cleaner, V&H True dual just added but had this problem with the previous Rinehart Pipes as well.
Bike started throwing codes recently and are as follows:
P - P0562 - Battery Voltage Low
P - P0563 - Battery Voltage High
U - 1097 - Loss of Speedo Serial Data to ECM - Code was reset and has not returned
PN - 32919-07A - I have not been able to figure out what this part number is as it is not in my parts manual.
S - B0563 - Battery Voltage High
PN - 68925-07 - Security System Module
SP - B1006 - Accessory Line Overvoltage
SP - B1007 - Ignition Line Overvoltage
PN - 67033-08 - Speedometer
Started to notice the engine light and/or battery indicator coming on and checked the codes. Historical codes only showing. Reset codes and made sure to clean, inspect and apply dielectric grease to battery cables, VR connections, checked for frayed wires, etc.
When the light(lights) comes on it is usually within th first 5 miles or so at beginning of ride. Sometimes comes on after that but not usually.
More recently started to notice at night that when the engine and/or battery light(sometimes just the engine light only) came on that my head light would burn brighter making my low beam look as bright as my high beam. This would happen for 5 seconds or so then go back to normal. Then last night I notice when the headlight got brighter my speedometer back light would go out until the headlight returned to normal and the speedo would return to normal as well.
Bike starts and runs fine. Checked the battery with a handheld load tester and voltage stayed above 10V. Also checked the battery voltage during start up and here are those results.
12.5 V ignition off
12.06 V ignition on
9.6 V while cranking
13.50 V at idle and goes up with increasing the RPM
Thought battery looked good so went on to check the Stator and here are those results.
42V @ 2k RPM
0 continuity on all 3 wires to ground
.1 resistance on all 3 wires to each other.
Stator checks out fine also so on to the VR where things get interesting, at least to me.
Checked the VR wires for voltage as follows.
2 wires showing 11.28 Volts using DVOM and one wire showing 11.20 Volts when grounded to the battery. BUT using a test light I can NOT get the test light to light up on ANY of the 3 wires? That part eludes me. Tested the test light to make sure it works and ran the same test 3 times. How can I have the voltage there with the DVOM but not show anything with the testlight? I understand that the older VR's should not have any voltage present checking with this method but I am not sure what voltages, if any, should be present with the newer 3 phase units.
My thinking is the VR is causing an intermittent Low/High Voltage situation and that is the reason for throwing the codes. What I don't understand is why does the Back Light on the Speedometer go out when the Headlight shines brighter? Is there a surge protector of some sort that shuts power to the speedo to protect it from overvoltage?
So what do you guys think. I have a VR ordered and hope that solves the problem but sure could use the input from the members here. I know should replace the stator at the same time as the VR but would like to fix the root cause first. :small3d023:
