How to test & remove the fuel injection control module (FICM) from a 2003, 2004, 2005, 2006, 2007, 2008, & 2009 Ford 6.0 Powerstroke Super Duty. Visit our site at www.CircuitBoardMedics.com for more information or to have us repair your FICM for P0611, P0261, P0264, P0267, P0270, P0273, P0276, P0279, and P0282 diagnostic trouble codes. These codes are not always present with a failed, low voltage, FICM. If your Powerstroke 6.0 runs rough until it warms up, then FICM repair is likely needed. This video shows how to test 4 pin and 7 pin FICM's. Circuit Board Medics will rebuild the FICM to run strong!

Having blown fuses problem with my bike, also sparking when i attach the power cables. i think this regulator rectifier is the problem! but as im not an electrical engineer i cant find a way to test it. after some research i thin i found a way to test it. but would like it if someone more knowledgeable knows:)

Testing Blower Motor Amperage and Voltage

Motorcontroller_10-26-2011.mp4 I had designed a very high power motor controller that originally ran using a 555 timer that was setup for pulse width modulation. However; Problems where found with 0% and 100% duty cycles, and issues with reliability of the 555 under this kind of use. A pic18F26J11 8 bit microprocessor was used for the PWM drive and would also be leveraged for the additional features required for protection circuits and some miscellaneous other tasks. The ten Mostfets are 61-65 amps at 200V rating providing a 600-650 amp motorcontoller with a surge capability of 2500 amps for 10ms. Two high power fast diodes are incorporated on the ends of the mosfet strings to handle back EMF from a motor. I think these are 200 or 250 amp rated (will have to look later) so I am hoping this is enough to protect the mosfets. A single NPN transistor is used to setup up the 3.3v logic output of the microprocessor to 10-12 volts required to drive a 15 amp gate driver chip which does the fast switching to keep the mosfets cool. This gate driver needs only 5.5 volts minimum to switch the mosfets high. However this driver needs 10-12 volts in order to supply that voltage to the mosfets for a good strong switching affect with 10v being optimal to the gates. I burnt up a LM317 adjustable voltage regulator with some of the mosfet power oscillations which was used to drive the logic circuitry so in this video a 12v zener diode with voltage drop resistors was used to power the pic18 ...

The magneto alternator of Royal Enfield Motorcycle UCE EFI G5 has 18 coil 3 phase stator that charges 12 volt battery. The alternator electric output is directly affected by the speed of motorcycle engine (rpm). Alternator generated AC of 15 volts when engine was running at idle and it increased to 40 volts as throttle was opened to high rpms.

This is a short video of the early testing of my new GAVR-15 AVR on my ST-10 Generator. You can see clearly it self starts easily with no capacitor or ballast required. The voltage regulation is nothing short of excellent, even handling a large bank of fluorescent lights on their own with no noticeable flickering. The other regulators I have tested have all needed an additional load such as a heater or similar before they could make a stable voltage while running these lights. This shows how well filtered this regulator's circuits are.

This video will give people a way to create a cheap DC Power supply from a new/used computer ATX power supply. Always remember electricity is very dangerous... and I mean, both A/C & D/C types!! Instructions: www.wikihow.com I like to have a DC Power supply for testing things like when I build HHO systems (Hydrogen generators used to get better fuel mileage in cars). Remember that car electrical systems generally produce a little higher voltage of around 13.6V - 14.7V which can generate amperage a little bit better than the ATX power supply system (controlled by a voltage regulator). So the ATX system would be an approximate testing system... not an exact one. ..
