Socalcasedog Posted April 10, 2011 Report Share Posted April 10, 2011 Got an 02 shee....installed an Electrosport 250w stator up grade. Floated the ground for DC conversion. Planning to install HIDs. Did a voltage check from rectifier and im getting 12v at idle. Plug rectifier into harness and now only shows 5v at idle. Unplug wire and it goes back up. Its got me stumped. The stock ligjts still pulse at idle like they tupically do stock. I really dont understand why the voltage drops so much just pligging it into the harness. Ive done voltage checks at the rectifier (with and without being plugged in), and at the factory light conectors. To quickly sum it up: Rectifier unpluged from harness- 12-14v(idle and rev) Rectifier plugged into harness- 5v at idle( at both headlights, tail light, and at point of connection of rectifier to harness) Im stumpped!!! Hoping its just something stupid. Please help if you can. I appreciate it a lot people. (tried to be as detailed as possible in my discription) Quote Link to comment Share on other sites More sharing options...
Socalcasedog Posted April 10, 2011 Author Report Share Posted April 10, 2011 Oh and sorry for the typos...big thumbs on a touch screen cell dont work to well.... lol Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted April 11, 2011 Report Share Posted April 11, 2011 did you hook the batt up and what gind of rect/regulator you using Quote Link to comment Share on other sites More sharing options...
Socalcasedog Posted April 11, 2011 Author Report Share Posted April 11, 2011 I havent even got to that point yet. 5v isnt gonna keep the batt charged night riding. Was actually gonna use a capacitor but no use in getting to that point untill ive got adiquate charging power first Quote Link to comment Share on other sites More sharing options...
ionroller Posted April 11, 2011 Report Share Posted April 11, 2011 If the voltage drop occurs only after going through the rectifier, that's most likely your cause. Check the resistance of it? Quote Link to comment Share on other sites More sharing options...
Socalcasedog Posted April 11, 2011 Author Report Share Posted April 11, 2011 im getting 12-14v out if the rectifier. Its only after I plug in the lead into the harness it drops. I stated that earlier. The light switch is off so I shouldnt have that drop in the lighting circuit. Again, ive check voltage before the harness point of connection and as soon as I disconnect it voltage goes back up. There is no sparking when I touch the connectors together telling me i dont have a short of any kind..... Quote Link to comment Share on other sites More sharing options...
ionroller Posted April 11, 2011 Report Share Posted April 11, 2011 put the ohm meter on the harness. Voltage doesn't magically drop with out resistance. Quote Link to comment Share on other sites More sharing options...
ionroller Posted April 11, 2011 Report Share Posted April 11, 2011 and what kind of rectifier are you using? Quote Link to comment Share on other sites More sharing options...
Socalcasedog Posted April 11, 2011 Author Report Share Posted April 11, 2011 got the stator and rec from the same company. Told them what my plan was and they floated the ground for me while I waited and sold me the correct rec for the application im doing. Called them this morning and they told me that I need to run the pos and ground wire to the same pole of the capacitor and run a dedicated pwr wire to the light switch and not to use the factory harness cause it wasnt built for AC. ive got electrical experiance but what worrires me is that I dont want the .5 farad cap to blow up in my face ya know. Guess im being over cautious. What are your thoyghts on that? Quote Link to comment Share on other sites More sharing options...
ionroller Posted April 11, 2011 Report Share Posted April 11, 2011 Just dont short the cap. They go boom!!! I think you need to run the output of the reg to the negative of a small battery (like 6 amp/hours) then run your lights from that. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted April 11, 2011 Report Share Posted April 11, 2011 when you say plug into the harness, do you mean you are grounding one wire of the reg/rec to ground, and the other wire your trying to feed into the light 12v positive for the switch (yellow)?

Socalcasedog Posted April 11, 2011 Author Report Share Posted April 11, 2011 Ya the y/r.....think I may have figured something out but wont know till after I get these customer cars done and can get the shee in the shop to work on it. Ill let you guys know what I find Quote Link to comment Share on other sites More sharing options...
Socalcasedog Posted April 12, 2011 Author Report Share Posted April 12, 2011 Well we figured it out, at least for the time being untill I mount the hid's and test them......added a chassis ground from the rectifier and now the capacitor is charging and im getting the same voltage at the headlight pig-tails as us comming out of the rectifier. Thanks for the imput though guys....i really appriciate it!! Quote Link to comment Share on other sites More sharing options...
Socalcasedog Posted April 12, 2011 Author Report Share Posted April 12, 2011 whats funny is the manufacturer said to ground the rectifier to my cap and not the chassis Quote Link to comment Share on other sites More sharing options...
AKheathen Posted April 12, 2011 Report Share Posted April 12, 2011 well, if they told you to connect the positive and negative to the same pole, then they are retarded.... yes, there are grounds on the frame that the lights use, but there is also the black wire. and, the wires don't care if they see ac, or dc. all the wires care about is that they get connection, only a certain amount of current, and that you pay the child support on time. chances are, you still have a problem with one of the black wires in the harness, and that can affect more than just the lights. i would go through the harness, find the problem, and do your upgrade to handle more current. so, you have a rectifier with 3 input wires? or are you just running the 150watt winding?
