No start issue

[Elmo Hayride]

The first time it blew Tail and Ignition. Now it will just blow Ig.

Yeah, the black/yellow is the B+ feed to the whole meter head. The blue wire is signal feed to the t/s controller. You said it blew a fuse...which one?

[Elmo Hayride]

It still blows the fuse. The actual wire injecting the B+ is the Blk/Yel (other wire for distance sensor). From all I see thats supposed to be gound.
If I leave the Lt. Blu and Blk/Yel off I can connect the speedo but still no Hi/Lo, Neutral, or Signals indicators.

What happens if you disconnect the light blue wire running from the reed switch and reconnect the speedo cable?

[Elmo Hayride]

Here you go.

[Elmo Hayride]

Troll, I'll scan and post one.

[Troll]

Sure wish I had a '99 circuit diagram...

[draconarmy]

was talking to my father in-law (gwychief) and he says he had a similar issue.  it ended up being in the clutch.  he says that the cable comes loose at the lever and this causes a safety to trip.  he just had to push the cable back into seat and tighten it down.

[Elmo Hayride]

Thanks Troll.
I put the speedo back on and taped off the speedo cable connector and left the cable off. Starts and runs fine but no Hi/Lo, Neutral, or Signals indicators working and also the fuel gague doesn't work.

Doesn't look like you will be able to take it apart. Getting a new reed switch might be impossible. The way these things work is actually pretty simple. The mechanical speedo has a part called a drag cup. It's basically a spinning pair of magnets driven by the cable. This works the needle against a hair spring. The reed switch is a glass capsule located near the drag cup. It's got a pair of contacts inside that are normally open. One of the contacts is magnetic, and as the cup turns, it pulls the magnetic reed into contact with the standing contact for an instant. This sends a square wave pulse to the turn signal electronic controller. After enough of these pulses, the turn signals shut off. My suspicion is that if you were to disconnect one of the wires to the reed switch, the no start situation would be corrected, but the turn signals would no longer cancel. You could do this while hunting for a replacement speedo head. Harley had these, and so did a lot of Japanese cars with mechanical speedos...they go bad in various ways. Sounds like somehow yours shorted to the drag cup.

[Elmo Hayride]

It's the point labeled Lb on the back of the speedo thats shorted...goes to the speedo distance sensor.

As I am not one to perform these types of surgery without first the consult of people who eagerly engage in dissecting problematic devices here I give you proof of how not easily this will go back together for your review. I may just have to mail this one to Troll for his enjoyment.

Like Troll said, The 99 service manual I have says the Speedo is serviced as a unit. It should not be taken apart for servicing so it is probably going to be a real project to get it apart and back together!

[Troll]

Sure wish I could see it. With mechanical speedos, the actual meter is usually crimped shut to prevent tampering with the odometer. The electronic ones come apart pretty easily, but there non volatile ram chip is pretty secure. There seems to be a short to the case that is causing the problem.

[Elmo Hayride]

I have it on my desk right now. Got most of the wires and bulbs pulled, just can't seem to figure where it splits. The frt metel bezel is bent aroung the top and bottom edges.

[Troll]

Sounds like it's time to take the meter assy. apart

[Elmo Hayride]

I recall that when everything was plugged in minus the speedo cable, everything worked fine. Hi/Lo beams, dash lts, signals, and pretty sure neutral indicator.

[Troll]

So you have 3 lights, a fuel gauge, the efi, oil and temp lights...and the meter illumination...What happens if you leave the speedo cable disconnected?

[Elmo Hayride]

It's a 1999.

[Troll]

What year is it...I have a R service manual.. I'll post a meter wiring diagram if it's the correct year

[Elmo Hayride]

Sorry John,
I mean meter as in speedometer assy. When the 3 plugs are connected there is +12V from the speedo connection on the back of the speedometer. If connected to the cable a dead short occurs to ground (cable side).

[John Hopkins]

Well after pulling and inspecting the fuse panel I decided to put the bike back together and try again from the beginning. All the power was fine until I put on the meter. Wouldn't you know, theres +12V coming out the back of the speedometer cable connections. At least the bike runs and I'll have some spare (future) parts coming soon.

Has anyone heard of this or have any ideas?
Dave

I'm not quite sure what you mean..but..

Meter to dc volts.

connect across the battery..read voltage..write it down..

Leave the red lead on the + battery terminal move the black lead to the frame..do you have the same voltage..If not run a jumper lead from the negative battery terminal to the frame or tighten the battery connections..

Tell Mom Thanks...I just may do it...

My Mom: "Ok, let me think... when the car won't start your supposed to... take off your shoe and hit the battery with it". Worked every time.
