New 250cc ZNEN Model headlight regulator question By thescootersolution (Read 1,743 times)

This question regards the new(or newer) ZNEN 250cc scooter that is most easily distinguished by its hatch-back access to the under-seat storage area. BMS calls it the L-Roar, SSR the Titan and Puma Cycles the Apollo.

These scoots have a module of some sort that has to do with the running lights and headlights that are not typically found on most scooters we see and work on. To the naked eye it would appear to be a CDI module based upon its housing, but our guess is that it functions as a regulator for A/C lighting in the bike. We have seen two different kinds, a smaller one that does not appear to control the running lights (only the headlights) and a larger one that does seem to control all the front /rear running and dashboard lights in addition to the headlight. Both have the same connector to the harness, so would appear to be interchangeable save for the differences noted above.

Can't find any info on these guys anywhere, and the techs at the distributors are not much help beyond selling us replacement pieces. In trying to troubleshoot some lighting issues we have on this model we are fairly certain it comes down to this part, but are unclear as to what the full extent of this part's functionality is and inevitably that will (if it has not already) inhibit our ability to address any lighting issues on this bike.

Just hoping to get some definitive info on this from someone(s) whose already gone down this path.

Thanks!

One of these units for headlight control is fairly popular and is often called a blocking diode or relay because of its electrical function. The smaller unit which has a short lead and a two pin connector is the more common blocking diode. The other less common unit looks like a 4 pin regulator/rectifier, which connects directly to the scoot's wiring harness. In either case we are talking about just 2 wires from the main harness. It sounds like the lighting wiring for scoots with the direct connect headlight unit is wired to run all lights while the scoots that come with the smaller control unit run only the headlights. The amount of lights that come on (headlights only or all lights) has to be a function of the wiring layout of the scoot. If jumping the 2 pins of the plug on the scoot harness causes the headlights or all lights to come on, then we are talking about a simple diode which is controlling a DC lighting circuit. The smaller unit should then be a good substitute for the larger unit. Many people, myself included, have replaced the blocking diode with a simple automotive relay whenever a replacement is needed. This also feeds about .7 volts more to the battery for charging purposes.

I believe this is the unit you guys are talking about and I hope this info is of some use.
