2007 EC 300 Speedo

Super Rat:
Where did you hook up the ground wire from your 9V battery?
My Acewell only has a yellow wire exiting from the center wire
bundle, along with the three tiny connectors. I assume these
are for 1) speedo, 2) RPM, 3) water temp.
I tried touching the (+) of a 9v battery to the yellow wire and
grounding the (-) to the mounting bracket. No go...
I can get a close up picture of the back side wiring sometime
this weekend for a comparison.
Thanks, Jeff in so.Cal.

I found this with a google search. Acewell wiring diagram.
http://s3performance.com.au/download...ng_diagram.pdf
this may be the solution to my delima.
Is it the same .pdf file that Super Rat was eluding too?

is that an easier way to add juice than a dc stator? on the trail tech site it says dc stator sold seperately. i want to add some kind of capacitor to run blinkers, without going to a bigger stator. im a noob, so im not even sure if im looking at this right..

Hmmmm... Now I am more confused than ever. After looking at Super Rats'
Acewell gage and comparing the one I have. They seem to be different
configurations of the same gage. The front of the gage looks the same.

The back of the unit has a different part number, BT280634005. This one is from
a 2007 TXT trials bike.

The wiring is different from the diagram(s) I've down loaded, and this is leaving me
perplexed.
As you can see from the picture. It has three connectors and one yellow wire
coming from the middle tap. The Green/Black is connected to the speed sensor
wire. And seems to match what the wiring diagram depicts. It is the other two
connectors that don't seem to match. I do not know what functions are
supposed to be hooked up to the Blue/Red and the White/Brown (or Purple)
wires. I assume these are for water temp....and ????? who knows. I doubt this
would be a fuel gage on a trials bike. According to the diagram the yellow
wire goes the the Coil or spark plug wire for RPM readings.

The outside wire bundles control the High/Low beam and turn signal displays
only.

This consists of two black wires, (joined together @ one pin) and two each of
Yellow and Brown, or Purple wires.
So I guess what I am asking if if anyone can tell me what the two connectors
are for and which ones are for the clock function + and -.
I guess me next step would be to contact my local Trials dealer or
Dale Malasek, the GasGas importer.
Thanks for any information or suggestions you can provide.

Mountain Thumper - you don't need a DC stator if you do what I described. Yes, what I did is much easier than replacing/modifying the stator. What I did will run lights and blinkers also, although you can still run lights on the existing A/C circuit.

slocalspode - the red and blue goes to DC power (red is positive, blue negative). The white and brown wires go to a 9vdc battery (white is ground) that runs the clock. The yellow wire with the bullet connector is the tach pickup. The wiring on yours looks just like mine.

Thank you for responding to my questions.
Let me see if I got this straight.
The red/blue needs 12VDC from the rectifier and
the white/brown needs 9VDC?!?!
Two power sources....hmmmm... I assume one to
keep the clock functioning and the other to power
the gage and LCD backlighting.

These are unique style connectors, (to me anyway).
I think I need to make a call to ElectroSport and see
if I can purchase some of these from their accessory
catalog. They make a 9V battery holder with the proper
connector, I believe.
Thank you for your help.

Yep, you have it correct. 9 vdc keeps the clock going.

I used a 9v transistor battery. Radio Shack sells the battery connector and bracket to hold it.

I cut off all the speedo connectors (except for the speedo pickup), soldered on more wire length and then used "normal" connectors to hook everything up.

cdn280 - I thought an arc welder on the trail would be pretty handy - you know trail repairs, etc.

Seriously, I was looking for something around 5,000 uf and didn't read the TrailTech description very well. It is 56,000 uf, about 10x more than I needed.

I'll probably replace it at some point. Didn't cost that much.

Looking a little closer @ the wiring diagram, I think the light in
my head is starting to flicker.
The Brown/Black keeps the clock running and the Blue/Red
is a switched, (on/off) function to turn on the unit.
I am assuming, (there I go again), that you could run the
whole unit on the 9V battery and install a switch on the
handle bar to turn in on/off. Otherwise I'd need to install
a rectifier, like you did, to provide DC power. I have a small
rectifier that came off my EC300 that was used to provide
DC to power the horn. It should be more than strong enough
to power the gage alone. I installed the same TrailTech
Rectifier/Regulator that you did after doing the floating ground
modification mentioned in another thread. Now my 300's system
is fully DC and runs a small 1.2Ah sealed lead/acid battery.
I am planning on using this AceWell on another bike some time
in the future.
Thank you again for your help, it is much appreciated.

Finally replaced the "arc welder" capacitor with this from Mouser Electronics:

539-CGO16V10000 16V 10,000UF LYTIC Mallory Screw Terminal, Computer Grade Electrolytic Capacitors

Works great and 1/4 the size.
