I'm going to have several electrical questions. 1st, Is pin #8, on the 14 pin plug at the relay board, the only switched 12v+ source in the engine compartment? TIA, Kent

Video on how to draw simple schematics
Question 11 question. Is this the internal A/C fan, or is it the electric fan on the radiator / condenser. |

Video on how to draw simple schematics Question 11 question. Is this the internal A/C fan, or is it the electric fan on the radiator / condenser. AC fan. It's a little too much unless I want to ride around with the windows rolled down. (IMG:style_emoticons/default/av-943.gif) And thx for the link. (IMG:style_emoticons/default/beerchug.gif) EDIT: OK, I watched the video and I already knew this stuff but boy did I find out something I didn't know. I had incorrectly believed that the energy of a battery flowed out the + side and returned via the - side. Shit, I had that backwards all of these years! The video says it flows out the neg side and returns on the pos side. Who knew? |

EDIT: OK, I watched the video and I already knew this stuff but boy did I find out something I didn't know. I had incorrectly believed that the energy of a battery flowed out the + side and returned via the - side. Shit, I had that backwards all of these years! The video says it flows out the neg side and returns on the pos side. Who knew? Current is standardized to flow out the positive terminal on a source (battery) through the load and in through the negative terminal. The electrons are now known to flow out from the negative terminal through the load and in through the positive terminal. Benjamin Franklin had a 50/50 chance when he guessed and made the standard. He just got it wrong (IMG:style_emoticons/default/headbang.gif) If you really want your mind blown consider that in semiconductors current is modeled as consisting of negative electrons flowing one way and positive "holes" flowing in the opposite direction. The direction of the flow of "holes" in a circuit matches Franklin's standard for current. As for circuit schematics, check out: http://www.123dapp.com/circuits (IMG:http://www.914world.com/bbs2/uploads_offsite/cdn.instructables.com-10819-1468470897.1.jpg) Make an account and you can build basic circuits from a box of virtual parts and a breadboard OR start in schematic editor and add components from there. You can then run a simulation of the circuit even including an arduino microcontroller complete with code. If you decide you want a circuit board made, the software can even route the lines to generate the artwork and you can order it online. It is actually amazing for free. |
