wrong wiring damage step module, 

Found P mosfet blown possibly short circuit on P-mosfet output with ground.

First I thought N-mosfet blown ,, But later found P-mosfet is the one.

EBP / ABS TRAILER POWER TESTER

making 24 to 12v step down power supply.

LM2596 is only supply max 3A. and 

even 3A is became too hot 

so instead of LM2596, I tried to make power supply using same principle like LM2596, 

using inductor and capacitor with maxium pwm speed of AT328p 4Mhz. 

faster then LM2596, so if i using right inductor and capacitor , then can make power supply using 30-50A mosfet. I successfuly create 4Mhz pwm using ARDUINO, and then when I using pulse signal 5v to make amplifed 12volt to control MOSFET. but signal became flat... I think, none of transistor or optocoupler, is not fast enough to fallow speed in my hand .I am not sure exist one. so last trried,  I connect to LM2596 output signal to mosfet Gate pin, Mosfet is not fast enough as well..

So far I fail.

but I tried to make LM2596 - 12v fixed one 

But I can not make  3-5 paralle circuit to make power supply 24 to 12v .../.

will not even power load on LM2596 , possibly burn one LM2596 first.

but first have to test and LM2596 need to precies.

HOW TO WIRING PWM MODULE AND WHY?

Sometimes, I am still confusing to wire up such as LED light with dimmer functions with using PWM module. MAYBE ONLY ME. ANYWAY PWM MODULE has lots of different LOOKS from like this fancy one to small and cheap on like this

 

but it has same function and do the same job. but most different is how much current they can handle.

bigger size maybe more bigger mosfet and bigger heat sink and that make more power can through.
Please check MAX current.

SO,

If I am installing simple LED strip light about 3amp of power then, I will use 5 amp fuse and choose PWM MODULE that can handle 5amp easy.

this is diagram for  KEMO MODULE

without any mark diagram make confusing me. this is need polarity mark like this.

One of Confusing of PWM module is Why they need to connect like this.

the reason is they need consumer earth to control PWM, not positive power side .

that is why need four wire.

SO I cannot use common earth or chessie body earth for consumer.

Consumer earth is controlled like : on, off, on, off, quickly inside kemo module.

so more explain

and this little module has four wire and easy to understand how to wireup.

BASIC 240V INVERTER SETUP WITH SECOND BATTERY

problem is my torque converter locked up (peugeot 308 engine stall and died at signal & shudder at highway driving)

Thursday After work the way home I experence My car go to limphome mode and stuck to 3rd gear and I could not drove more then 80k and RPM was like 5000 with diesel engine, .......
bad simptom was started 2month ago it was not seriouse, and now I think problem is my torque converter locked up (peugeot 308 engine stall and died at signal & shudder at highway driving) because only I think of engine stall at stop, is clucth locked up in this case is torque converter and when highway driving about 5th or 6th gear seems shuddeing like engaging disengaging problem I thought my self maybe oil problem, but now I thinking this is the proplem'
TCC valve / solenoid.

My peugeot has Aisin AM6 auto transmission. when I search the parts I found that also called TF80SC.
other manufactur use same Aisin Transmission but different name on it.

Common Complaints with AW 6 Speed FWD

Complaint:

• Harsh up or downshifts
• TCC slip, fluid overheat
• RPM cycling at low speed or coast

Cause:

• TCC clutch is not releasing or loss of TC modulation control
• Torque converter clutch control valve bore worn and/or secondary regulator valve bore worn

Diagnostic Procedure:

• Monitor converter release pressure to verify the clutch is being controlled. If release psi remains low (see chart) during up/down shift, the control valve is not stroking. Compare the release pressure to TCC solenoid amperage. For overheated conditions, also monitor cooler flow (see chart).

and I suspect and I hope is valve solenoid it self not valve body or valve worn otherwise it has to change all valve body.

so I give it shot
