Electrical wiring and charging system help? Answered
im working on a electrical upgrade for a power wheel. Im hoping someone can take a look at it and tell me if it looks ok, or if they see a problem with it. The mod keeps the 12V 12Ah system, but adds an additional 6V 1200Ah SLA Battery wired through a realy to allow a 18V boost when the Switch is triggered momentarily. Ive also attempted to add the following features:
-6V Battery meter for (NOS) Battery
-12V Battery Meter
-2 Remote fired Nerf Guns
-2 Small front speakers with a 3.5mm jack and a usb portfor an MP3 Player
-2 working switch activated headlights
-2 working switch activated fog lights
-2 working brake lights
-18V nos Button for a momentary boost
I have it drawn to use a 12V charger and a 6V charger, because the batteries will obviousely drain at different rates. I only have a basic knowledge of how relays work. My biggest concern is the chargers. Will they charge the Vehicle the way they are, or do I need to add another relay so that when a charge is detected i t disconnects the "ignition". Also if I have all of the voltages correct. the regulator breakdowns are on the right along with the relay info. Thank you for any help you can provide.
Added another drawing for some updated ideas.
I know that the DPDT coils are only getting 6V. ignore the DPDT part number and specs. i was able to find 6V DPDT relays.
-Also added three supporting photos, charging, run mode, accessory mode. (Black lines have no connection in supporting pics, except main ground, which is also black)
- Had to redraw, the DPDT's I found could only handle 15A per contact, and im pretty sure the motors alone draw around 18A. So back to lots of SPDT's
Heres a schematic for the main system stopping at the terminal board. im not worried about the lights and accessories, those i know how to wire, Please let me know if this will work. I apologize in advance, im not very good at drawing schematics, thats why i stick to drawing the physical layout.
