Using MightyBoyEV - Project issues and resolutions.....
|After one month: Oddly enough no electrical, electronics or battery issues to date.....|
|Windscreen wipers hitting windscreen rubber when used on "fast" speed setting||Adjust wiper linkage arms (reduce travel)|
|Selecting of 2nd gear by accident....||Fabricate an bracket underneath the gearshift assembly to act as a lockout for 1st and 2nd gear|
|Increase rear vehicle ride height by 50mm (cosmetic only)||Fabricate new adjustable shackles and change rubbers over polyurethane bushes - much better look!|
|Improve throttle "feel"||Add and adjust a third light (non linear) spring to the PB-6 pot box arm (also acts as a third safety "return to off" safety spring)|
||Replace original faulty brake lamp switch with new after market switch unit|
|July 12th 2009 general update: Still no issues to date - batteries and performance have improved now that the pack has been "Run In" a couple of months - easily more range then I need as a daily vehicle and only seem to be using 40 to 50% DOD. Heater takes the chill off nicely on our cool (4 degree) Adelaide mornings. Now have lowered the tyre pressure to 34 lbs and get a much better ride without noticing much (if any) difference in consumption (k-h/km). No charging issues with the Delta-Q to report - all batteries seem to balance nicely.|
|Cheap older tyres showing signs of delaminating....||Upgrade tyres (and Wheels)
check them out here!
Certainly improves the ride as well....
|“Cycle Analyst” display not showing - but backlight on?||Here is the fix......|
|Squeaks in the rear suspension!||
Replace the aftermarket replacement rear spring bush rubbers with the
correct Suzuki ones and turn-up new centre S/S inserts to suit.
|December 2009: Fix for noise (RFI) picked up on AM radio band||Fabricate a steel enclosure (a shielded box...) - Now all good....|
general update approaching the first year of use: No major
issues to date - batteries still performing fine and staying balanced
with no problems. Slight increase now noticed in battery sag (maybe
.5 volt) when compared to drawing the same high end currents a year
ago. Would be nice to have better battery technology but will hang in
there for a better overall solution and price point - will also look at
going CAN (mainly as a learning curve for me to play with).
I will also continue trying to reduce weight, rotating mass and rolling resistance with the aim of breaking the 80 watt-hour/km figure. I currently am looking at some very light 12" by 4" Alloy rims that should prove useful in achieving this.....the Mightyboy is so light all these factors can make slight improvements - smaller/lighter wheels and reduced tyre weight included. Switching to modern battery technology would reduce the overall weight significantly and hence go a long way to achieving my target..
|March 2010: Upgrade to light weight alloy rims (rare factory optional extra of the day)||Light weight rims and Light weight rims - part 2|
|April 2010: Poor performance after 1500 w-h of use||
Replace battery number 6 - excessive voltage sag with old battery...
