Warning! This is a VERY long post, and most likely going to be a VERY long thread. Get a drink, grab some food... or just skip it if you'd prefer. ... But, I'd really appreciate the help
All:
I apologize for the delay in replying. I've been out checking and rechecking the bike. I think I've managed to check the same wires 50 times today. I still am experiencing the same issues - in fact I don't know if this is a good thing or not but the click with no start seems to no longer be intermittent, but an all the time thing. Of course I haven't really ridden the bike, just let it run for a bit to recharge the battery and test the charging system.
I appreciate everyone's help and suggestions. Keep them coming! If no one minds, I think I'll use this thread as a little log of how it progresses. If I ever get it resolved maybe it will help someone else out in the future. Besides it helps me to put all this down in writing to understand what exactly I found - or at least think I've found.
The Clymer manual did arrive today, and the troubleshooting suggestions it makes for my symptoms were very helpful, if a bit confusing. The wiring guide re-enforced what I knew of the wire paths:
Current goes:
Little black cable from battery -> junction box -> red wire -> follows harness to console -> junction box -> red wire -> ignition switch -> orange wire -> follows harness to starter relay -> green wire -> starter
Added to what I put in the first post here is what I've discovered today:
1. It WILL start EVERY TIME when I jump start from my truck. I must have jump-started the bike 12 times today.
2. It DOES drag a little when starting from the jump-start, but ultimately turns over.
3. My volt gauge built in to the fairing normally shows between 11 and 12 volts, with the jumper-cables attached and the truck running it shows 13-14.
4. After the bike has been started and the jumper cables disconnected the volt gauge in the fairing continues to read 13-14 when I give it a little throttle, 12-13 at idle.
5. The battery has continued to test 10.5 to 12.5 volts depending on how much I've had the bike on for testing.
6. When I connect a jumper cable from the positive on the battery to the starter (giving another path for the current to travel) and press the start button it DOES NOT start. It only clicks (a little louder than normal), but does not turn over.
7. With the battery cables disconnected I checked the continuity of the battery cables with the multimeter. I connected the positive to the end closest to the battery, and the negative to the end at the starter. I set the digital multimeter to 200 (not 200k, just 200) ohms. It read approximately 1.0 - 1.2.
8. The negative cable read the same.
9. I did a voltage loss test (positive contact from the multimeter on the pos. terminal of the battery, negative contact on the multimeter touching where I'm testing) from the positive battery terminal to the end of the battery cable attached to the starter. With the multimeter set at 20 DCV it read less than .03
10. I did a voltage loss test from the positive battery terminal to the junction box where the little black wire comes in from the battery and goes in to the red wire that carries the current to the console and the ignition switch. On both terminals on the junction box it read less than .03.
11. I did a voltage loss test from pos. battery terminal to the orange wire that would normally be plugged in to the starter relay (runs from the ignition switch back to the starter relay. Has no voltage when the switch is in the "off" position). With the ignition switch in the "Ignition" position it read right around .20. Sometimes .21 sometimes .17. With it in the "off" position no voltage was read.
11a. Voltage is between 11.5 and 12.5. When the jumper cables are attached voltage is between 13.5 and 14.5.
12. Voltage loss test from pos. battery terminal to green wire that is normally plugged in to starter. With switch in "ignition", and pressing the "start" button it reads between .17 and .22. No voltage when not pressing the start button triggering the starter relay.
12a. Voltage is from 11.5 to 12.5 depending on how much I've been draining the battery with the start button pressed. When the jumper cables are attached this is between 13.5 and 14.5. Can not be tested when the bike is running.
13. With the battery disconnected, I did a continuity test from the pos. battery wire connector to the orange wire (unplugged from the starter relay) it read 1.0 to 1.4.
14. Can not test continuity to the end of the green wire because I need the battery hooked up to trip the starter relay.
15. While testing the voltage from the terminal on the starter where the battery cable connects to the terminal that goes in to the starter when I press the start button the voltage does drop up to 2 volts.
16. I honestly can not make a lot of sense out of the readings I got from the starter. Following the voltage loss testing instructions gave me all sorts of odd readings.
For example. When I put the negative connector of the multimeter on the negative battery terminal and the positive connector on the end of the green wire while it is connected to the starter (I kind of slipped it in there touching the end of the green wire until I got a reading) it reads 11 - 12 volts even before I press the start button. When I press the start button this drops to 4 volts or so. How can it be reading voltage before I press the button? Why does it drop when I press it?
17. I'm more confused now than when I started at 10am.
Questions I Don't Know the Answers To:
A. Why does the bike start every time on a jump start, but not from the battery? The battery is around 12 volts, the voltage with the jumper cables is between 13 and 14. That doesn't seem like it should make that much of a difference.
B. Would jump-starting the bike "power through" bad battery cables?
C. Does what appears to be acceptable continuity and voltage loss tests tell me the cables are ok?
D. Does the same mean the wiring in the harness (red, orange, and green wires) are ok?
E. Would jump-starting the bike "power through" issues going on in the starter with the solenoid or the starter itself?
F. If the wires in the harness are bad, would jump-starting "power through" those issues?
... If you can't tell the fact that it jump starts every time, but won't start with just the battery is confusing the heck out of me.
Next Steps:
At this point I don't know what else to try. I've disconnected, and reconnected the battery wires so many times I hopefully would have gotten a good connection one of those times. Otherwise, the cables are actually bad, and I don't have spares here to swap them out to see.
The Clymer recommends taking the starter off the bike and performing some bench tests to see if it's actually the starter or the solenoid. Unfortunately, I do not have the facilities to do this properly and would rather not make the situation worse by screwing something up.
Unless one of you have some more suggestions for me to try, or I find something else to test, I think I might have to break down and take it in to the local Harley dealer so they can take this further.
You can bet they're going to get a print out of this and my first post, though. I'll be darned if all this work doesn't at least not get read by the Harley tech there.
.. So much for it being a simple starter relay or a new battery.
Well, those of you more knowledgeable than me? Does any of my "process of elimination" point you more or less to the cause? As usual, thanks in advance for any help or suggestions.
