you're in no hurry aren't you?NeilP said:don't be tight with the crimper. just buy your own. and don't buy that second one from Amazon, it is more expensive and on ly does one part of the crimp at a time.
seems you haven't used it yourself. all my crimps are top notch and i've done some hundred at least. this is a top quality crimper and a 100% 5* rating proves that all other ppl who bought it think the same.look at the advertising image from the amazon site ..and the quality of crimps that more expensive Amazon one produces. If I did a crimp like that I'd cut it off and start again!
teklektik said:How to Refresh Corrupted EEPROM Settings
Repair of corrupted EEPROM (CalOverwrite) can be achieved using the CA3 Setup Utility.
(Formerly, this was accomplished using the older separate Firmware Update Utility by means of a 'dual flash' technique. This new method described here is preferred.)
Until Grin Tech web site directions are posted, here's a temporary procedure to correct corrupted EEPROM using the newer utility:
Done!
- Download and install the latest CA3 Setup Utility from the Grin V3 web page.
- Hook up the USB cable and launch the utility.
- If a settings file was saved prior to the corruption incident, load it into the Setup Utility, otherwise skip this step and use the defaults.
The Setup Utility initially loads the data\default.hex setup file which contains factory defaults for all parameters in EEPROM:
- those that can manipulated with the normal V3 console buttons,
- hidden parameters only manipulable with the utility, and
- a number of device-specific calibration values set at the factory.
These factory calibration values typically vary from the specific device-specific values by a few percent and give the best accuracy. However, replacing them with generic defaults will have minimal impact. Ideally, if a settings file from the same device has been saved prior to the corruption incident, then it may be used in lieu of the default file to restore the unit to the original factory calibration.- Normally the Battery and Calibration Categories will not show the factory calibration parameters ('Show Protected Settings' is unchecked).

- Enable 'modification and write' of all shaded parameters by enabling the checkboxes.

- Make any desired setup modifications.
- Write the complete suite of parameters to the V3.

Would the fix above work for this? And what would I edit, the voltage scale?
If the 'stock' number is 31.18 V/V, then should I do the math (52/50.9*31.18=32.04) to get the new number of 32.04 to put in there?
Yes, that procedure will work as far as accessing the protected values is concerned, but the part about flashing with generic values (and losing your per-device settings) is unnecessary and not a good approach in this case.Grin Tech V3 page said:VScale: This is used to calibrate the voltage display. The factory calibration is about 31V/V.
Yes you can. Present behavior is as expected for the way it is wired.ColinB said:Can I connect things to have e-brakes, cruise control, and regen braking?
Presently I have the throttle going to the CAV3, and the brake to the Infineon. Applying the brakes cuts the motor, but does NOT cancel auto cruise!
Please review these sections of the Guide for details on proper ebrake wiring:Unofficial Guide said:IMPORTANT: Do not use the auto-cruise feature unless ebrakes are installed and wired to the Cycle Analyst EBK input. Using auto-cruise with the conventional ebrakes connection to the controller will not disengage auto-cruise when brakes are applied and may cause a potentially dangerous runaway situation as soon as the brakes are released.
Your throttle stop has been mashed back requiring re-adjustment of the CA.ColinB said:The bike now drops out of cruise control fairly regularly. It's been working fine for a few thousand kms. The manual says cruise is cancelled on throttle application or ebrake input. (If ebrake is plugged into the CA.) What else could cause the cruise to drop out?
Unofficial Guide said:3. Auto-Cruise Dropouts: Sporadic dropouts in auto-cruise operation may be traced to a ThI->MinInput voltage offset that is too small. See ' 4.7 Test Throttle and Limit Settings (Interpreting Limit Flags)'.

justin_le said:izeman said:only power and gnd. nothing else is needed to boot it.
That's correct. Normally putting a momentary short on the 5V throttle rail would cause the CA power rail to trip and the CA to reset itself without much consequence. But if was sustained for a length of time then it's possible that the small p-channel mosfet that controls the 5V bus going to the throttle output, LCD screen etc. was fried. When you apply power right now to the CA, do what voltage do you see between pins 1 (5V) and 2 (gnd) of the throttle plug? If there's no voltage here, then check between pins 1 (10V) and 2 (Gnd) of 5 pin PAS plug. If you DO see about 9-10V on the PAS plug power, then the linear regular is fine and you've likely just damaged the 5 p-channel fet that switches the 5V rail. If the don't see voltage on the PAS plug either, then the issue is likely further downstream on the linear regulator.

roadrash said:Not sure if you missed the part where i changed the board out to one that i know for sure works.
With just power and ground hooked up the display backlight comes on and flickers a bit. I just checked and there isn't any power on the 5v ...I do have power on the 10v
With this new board i have not once had the 5v hooked up btw
