Loudcivic Posted April 30, 2011 Report Share Posted April 30, 2011 i think people kinda knew about it but not fully. ive been reading things just never done it. after seeing you do it that got me wanting to do mine lol. thanks 2015 silverado crew cab nothing atm but soon...

Mr. Darkjustice Posted April 30, 2011 Report Share Posted April 30, 2011 oh shit, i looked at the diaphram, i know what you're talking about now... maybe i need to put the diodes there?? It's not in a diagram in this thread man late model GM vehicles read the load off of the ground (what are you talking about 1/0 this has to do with the cars electrical) and then charge accordingly. Read up on it... There are three modes, economy (no charge), charge (12.9-14.7'ish), and start (15-15.8'ish) which tops off the battery. If there isn't a load and it's hot out the ECU tells the system to stop charging to conserve fuel or low charge (12.9-13.x). Maybe the cars don't have it, but I thought all models did as of 07. The only way I know of to force it to charge is to run one of your amps through the pickup which is on my list for this spring (going to run 4g from my 4 chan through it so it sees a load). i was told somethin like this about my fusion also. except i was told this about running any vcm Fusion With A Stetsom 4k2d on 2 DC XL 15s tuned to 31hz and Subs and ports forward The Revolution Was Not Televised But There Is This Thread(clicky) Dr Merkenstein is my 360 gamertag and my profession.

Purplehaze Posted April 30, 2011 Report Share Posted April 30, 2011 @ Loudcivic - Is there any way you can help me find a spec sheet for my car? I haven't had any luck. It's a 2002 PT Cruiser 2.4L SOHC non-turbo automatic. I REALLY want to do this to my car, if it is possible. I appreciate any and all help!

stavo Posted April 30, 2011 Report Share Posted April 30, 2011 i just did my ford taurus and i used only 1 3amp diode and im at 15.7 cold and 15.3 warm . the wire was orange Link to comment Share on other sites More sharing options...
Loudcivic Posted April 30, 2011 Report Share Posted April 30, 2011 wow nice results for sure. just remember its not gonna benefit you a lot if your running stock alt unless its a decent amperage alt. 2015 silverado crew cab nothing atm but soon...

la negra Posted April 30, 2011 Report Share Posted April 30, 2011 loudcivic let me know and take a pic if you can. im just tryin to help if i can. it may work it may not i appreciate your help heres the pixs Link to comment Share on other sites More sharing options...
Loudcivic Posted April 30, 2011 Report Share Posted April 30, 2011 purplehaze: im not sure on yours. this is wut it says about your charging system. also this is for a 2003 but should be the same since nothing changed The Electronic Voltage Regulator (EVR) is not a separate component. It is actually a voltage regulating circuit located within the Powertrain Control Module (PCM). The EVR is not serviced separately. If replacement is necessary, the PCM must be replaced. OPERATION The amount of DC current produced by the generator is controlled by EVR circuitry contained within the PCM. This circuitry is connected in series with the generators second rotor field terminal and its ground. Voltage is regulated by cycling the ground path on SBEC vehicles or the power side on the NGC vehicles, to control the strength of the rotor magnetic field. The EVR circuitry monitors system line voltage at the PDC and calculated battery temperature or inlet air temperature sensor (refer to Inlet Air Temperature Sensor, if equipped, for more information ). It then determines a target charging voltage. If sensed battery voltage is lower than the target voltage, the PCM feeds the field winding until sensed battery voltage is at the target voltage. A circuit in the PCM cycles the feed side of the generator field at 250 times per second (250Hz), but has the capability to feed the field control wire 100% of the time (full field) to achieve the target voltage. If the charging rate cannot be monitored (limp-in), a duty cycle of 20% is used by the PCM in order to have some generator output. Also refer to Charging System Operation for additional information so it is regulated a totally different way then most. the pcm regulates it so i cant help with this vehicle since i dont have no experience with that type of charging system. if i had one in front of me to work on i could figure it out but not by just reading. it says about the target voltage so that would be between the battery and pcm. if you could figure out a way to trick it into thinking the battery is only reading say 11 volts then i would think it would bump up your voltage. you may be able to put a diode in between the wire that goes to the battery that tells the pcm what voltage thats at but im not sure which wire that is. this diagram is kinda hard to read. i will look at it some more but here it is for you to look at 2015 silverado crew cab nothing atm but soon...

Purplehaze Posted May 1, 2011 Report Share Posted May 1, 2011 the pcm regulates it Man I really appreciate your time. I came up w/ the same conclusion, I think the key is what you said up there. I think I'd have to wire in some sort of by-pass to the pcm. If I knew more about electronics, I'd say it could be done. But unfortunately I don't, so I'LL probably end up having to go with a mod from MLA. I know I really could use that extra voltage.

bdubii Posted May 1, 2011 Report Share Posted May 1, 2011 ^ that kinda sucks dude. If I knew of a way to bypass it I would suggest it but I don't unfortunately My build, four 15's walled: http://www.stevemeadedesigns.com/board/topic/106855-07-tacoma-walled-off-with-4-15s/page__p__1487297#entry1487297 Link to comment Share on other sites More sharing options...
