Frame is version 20, charger is 24 and I can not identify the version of ECM and throttle.
The controller's model is zk2430hb4-fs. It has a 4 pin throttle connector with yellow, red, green and black wires.
The throttle is variable with 5 wires, 2 of which are black and go into the same pin in a 4 pin connector. Wire colors are 2 black, red,green and orange.
Are those two supposed to be used together?
I measured the voltage at full throttle when being held-23.5V and yellow light stays off. Both batteries perform identical when measured separately.
However when riding it drops to about 21.3 and the low light comes on under 23V.
My charger provides 27.7V when hooked to a voltmeter and 26V when charging the batteries. They are rated to be charged at 14.4-14.7V each. Is it possible I need a couple of volts more to fully charge the batteries and have the voltage stay above 23 when riding?
As to the breaker issue I replaced it with a 30A fuse and it hasn't gone off yet. Is 30 too much?
Razor engineered the E300 scooter to have a 20 Amp circuit breaker. Installing a 30 Amp fuse could cause problems due to the wiring not being able to handle that much current. A 30 Amp fuse could also put the speed controller at risk of overheating if the scooter is used to go up hills because the 20 Amp circuit breaker is supposed to trip under these type of conditions and a 30 Amp fuse would not blow at the same current level as a 20 Amp circuit breaker.
Thank you. I bought a 28.8V charger and it is much better. The low light only comes in later in the run. I also put in a 20A fuse and that has been fine so far.
