This Kawasaki Ninja Quad was one of first two battery powered ride ons in the fleet. It was free along with the now Modded Safety-Orange PW JEEP. The quad was painted with Krylon Fusion Safety Red and Gloss Black this past spring. Although it is a bit scuffed now :) The #3 gearboxes were replaced with #7/21Ts. This probably doubled the speed of the quad. Info on modding these old quads to #7s can be found here for anyone interested.
Main ESC build is nothing out of the ordinary. Using the common YK31C 24V 500W controller with a twist style hall effect throttle. Used a USB cable to extend the throttle cable to the ESC. PW factory accelerator now used for braking/emergency shut down in the event of ESC failure. Factory wiring harness removed leaving only the shifter. New harness built with 10 gauge and 16 gauge wiring. No use of the modular connectors.
Simple lighting on this quad. No strobes or wig-wags. Headlamps and tail lamp turn ON with ignition key. The front headlamps are controlled from the ignition switch NO terminal. The tail light is powered from the pilot light circuit. The flood and spot combination for the headlamps were chosen for width and throw for night rides.
To drop the voltage from +24v to +12v for the head and tail lamps two inexpensive L7812 voltage regulator were used with TO-220 heatsink. This saved from using a +24v to +12v stepdown and running more wiring. The datasheet for the L7812 can be found here.
Here are a few pictures of the build along the way! Nothing too in depth though.
21Ts mounted in rear pan. Soldered 10 gauge wire to motor leads and terminated with bullet connectors.
Overhead view of ESC, Brake/Reverse relays, wiring harness routing and shifter.
YK31C controller mounted above relays. Mounted with nuts and bolts. Did not want screws sticking out of the body.
All connections made. Looks a bit hairy but not too bad. Everything easily accessible. No use of the modular connectors.
See not that bad.
Batteries and ground distribution. Batteries fit nice and tight!
What's hidden behind the front faring. You can see where I sleeved the handle bar with PVC section so the hall effect twist throttle would fit securely.
More pics of handle bar/throttle and shroud modification.
Front head lamps. Spot on top flood on the bottom.
Tail lamp mount location.
'Complete' with headlamps turned on.
We will see how long these stock 540 motors last. If/when they happen to blow an upgrade to BaneBots 18v motors will be in hand. A voltage meter may be installed at a later time. Not sure it needs anything else unless the batteries have too short run time.
Turned out very nice IMO. Waited until all the parts and materials arrived before working on it. So the build went very quickly once started. It also was not quite as in depth as the Apache/Gaucho build which made it go quite a bit faster. These ESCs builds really are not difficult and definitely worth it.
Thanks for looking. Will try to get a video and some night pictures of the lamps soon.
