trail tech regulator not charging enough

I don't know that the trailtech regulator is going to help your situation. The SEM stator uses separate lighting and charging coils. Being that the HID runs off the battery you are not using the lighting coil for the headlamp any longer. You are double taxing the charging coil in a setup that was marginal in the first place.

hello.

I upgraded my regulator to trail tech because im using hid xenon front bulb. After i installed it i noticed that if i drive with lights on battery voltage goes down slowly, so it doesnt charge enough. Any ideas what i need to do to get it work correctly? only thing thats on my mind is to do extra ground wire from battery to earth carousel. without lights it charges the battery about 13,2v.

The SEM stator has three outputs, one for the ignition, and two for lighting/charging. The lighting coils are 70 Watts each.

The original lighting ckt is AC and only uses a regulator to maintain correct voltage for the lights.

The other ckt goes to a regulator/rectifier that not only regulates voltage, but also rectifies it to DC voltage that the battery uses, as Berger mentions.

If you have the universal TT 150 regulator, you should be able to tie both the yellow output wires from the stator together, and then into the TT 150 regulator. You need to verify this with UHE member SPARKS, but, I am sure that is what he had told me sometime ago. In this way, you will have a full 140 watt capability as opposed to only 70 watts.

As it stands right now, do you only have one of the yellow stator output wires connected to the TT regulator?
