Not to high jack Ron's thread, cause we did, but that's all me Chubs, I'll send ya a PM for proofOh come on now! your socks don't belong in your pants!!
Lost speedo ???

With the values and the rectangle on the schematic, I would say those are resistors......
...a varistor. By definition.
Voltage dependent resistor, protects vs over voltage. It's more like a diode.

Agreed. Look over to the right of those and you can see the squiggly lines that's a resistor symbol too. They must have drawn them different for a reason.
I suspect the ones the OP is asking about are internal on his EHC but I've never dealt with an 03 myself so I'm really just guessing.
A resistor on his +12 power line to his speedo sensor might fix it. I however don't know what amperage to use not a clue what that thing is capable of. I suspect not much

Nope, the speedo has not been replaced. The tach (Autometer) Curtice's mount etc. I'm going to do a bridge rectifier
to pull any AC voltage from the alternator, this means pure clean DC voltage. That's where I am as of now, all I have
to do is find the right Radio Shack ???? IF that's possible here in ReDnEcK city
I have been told that the EHC sends +12 volts but who knows what Dog did?
A resistor makes sense for the LED's, OH, I did call Autometer and they said those
speedo's ( 02, 03 ) "should be 12 volt without resistors" I'm even thinking about
A NEW Autometer speedometer, at least IT will have a warranty.

It's a thermistor I believe,WHAT THE FUCK IS THIS SYMBOL ?? it's all over the schematic
At first glance you would think so ..but come on Chubs, whats a thermistor doing on a speedo sensor or a brake light? You're better than that!

Thermistors also regulate voltages and amperages through different temperature ranges. Some regulate according to the temperature of the circuit. I believe that is what happens when the bike won't start till ya heat it up with a heat gun?At first glance you would think so ..but come on Chubs, whats a thermistor doing on a speedo sensor or a brake light?

You should have very clean DC from the battery directly and didn't you run dedicated power and ground to the sensor, from the battery already?Nope, the speedo has not been replaced. The tach (Autometer) Curtice's mount etc. I'm going to do a bridge rectifier

I suppose it's possible the speedo is shorting out and backfeeding voltage to the sensor....I can't imagine if you ran a dedicated power and ground directly from the battery you have had that many voltage spikes in such a short span.
Where's Shannon? he works on these old doggies

I got news today that said sometimes the speedo would intermittently loose ground
and the sensor couldn't handle it. Autometer doesn't like to talk about it other than
Big Dog brought them the "design" and all they did was build them to BD specifications
good or bad (electrically speaking) kinda like what they did at ThunderHeart. I'm waiting
for Shovelheadkickers auction to end. I think I will be calling Autometer again.
Thanks for all the input from you guys EXCEPT for the pregnant guy photo
