Having trouble with charging. all wires look to be in order. It has 12 volt delco Remy genny and voltage regulator 15 volts from regulator wen running 30 0 30 ammeter doesn't move much.is the 3 position light and charging switch and 30 0 30 gauge capable to run a 12 volt system

run wire from generator through Amp meter - not through light switch , allow the regulator to monitor charge . Any draw , ignition , lights would be drawn off the - side of amp meter . ( this would be with a key or shut off switch in system ) 3 wire regulator - NOT cutout relay on generator .

12v systeems do NOT use the light switch.. Switch contained a RESISTOR to help controm amp output of the 6v generator... A 12v system needs a VOLTAGE REGULATOR.. If the Generator is putting out voltage and you have EXCESS charge, then the REGULATOR is not set right.. Sometimes the easy way out is to get a new regulator as compared to trying to adjust it. 

If you need more PARTS to fix the generator system, you might consider a 12v alternator with INTERNAL regulator... Very simple and effective..

12v GENERATOR system with REGULATOR...

Exactly where are you measuring this 15 Volts? If it is at the battery, then yes, it is indeed charging the battery.

Please define "doesn't move much". If the battery is getting 15 Volts then it is probably fully charged. in which case the ammeter will not move much; in fact, it should read almighty close to zero when the battery is fully charged.

If you discharge the battery to a very low level then a 12 volt generator may peg a 30 amp gauge for a while until the battery gets charged up again.

As Steve mentioned above, a 3 position light switch has no business being used in this application.

The battery wire is going through the meter but the L wire is going through the headlight switch. My 15 volt reading was straight off bat post of the regulator

The generator and regulator are both working correctly. 15 Volts is a bit high but if you are only doing short runs it will cause no harm. If you take it out in 100 degree weather and cultivate crops with it for 12 hours straight it will overcharge the battery so best to turn on the lights.

I prefer to take the reading at the battery because that is what you are actually trying to charge.

Which direction, does it stay on the Charge side or does it go to the discharge. Also, is this a Negative ground system or is it still Positive ground?

Your L wire feeding lights and ignition is fine.

I should have been more clear in my previous post about the 3 position light switch; it is ok to use it to control the lights, but NOT ok to use it in conjunction with a bona fide regulator such as you have. It sounds like you are using it correctly; though, just don't attempt to connect the resistor on the light switch to anything, it is fine to leave it in place (unconnected) or remove it if you wish on your 12 Volt system.

some regulators have 4 terminals.. the "L" wire is a hot wire connected to the "B" terminal and does not go thru the regulaltor.. It would be the same as connecting the headlights to the amp meter terminal...  no problem..... like Les said, you normally expect to see a little less than 15v... Its possible your voltmeter is old ( or are you using a digital) and you really have 14 or 14.5v .... either way , 15v is not a BIG problem..

to test a generator... put your volt meter in the A terminal of the generator... best to remove the wire on that terminal that goes to the regulator.... other lead of volt meter to GROUND/ FRAME / neg battery terminal..engine running, take a Jumper wire from the "F" terminal and touch it to the GROUND...

this will BYPASS the GEN and FIELD coils of the regulator and let the generator run wide open...the battery itself acts as a "regulator"... tries to keep the generator down to 15 volts... when you take the regulator wire off the "A" terminal and the battery is no longer connected ( to the generator) .,  the generator might put out 20- 30 volts...

At what speed? It won't charge at all at low idle speeds, rev it up to wide open throttle. When all is correct, this will energize the cutout relay inside the regulator which will then send the charging current to the battery.
