WRONG VOLTAGE Hi, i have made the classic mistake of powering my iriver h320 with 12v rather than 5v. it now does nothing. have i damaged it beyond repair or does it have a fuse or something that protects it from permanent damage from too much power? Any help or advice greatly received.

No as long the player is not damage you can still match the voltage because the 12v is not going to turn on or work properly on the h320 because the voltage is not right. Unless if you have a closer voltage like 4.5v or 5.2 v it will be good it will work.

Example:When i bought my pda it did not come with adapter so they gave me an alternative adapter is supposed to 5v but they gave me 6v to try out first it work then second try i turn my pda using the ac it have problem with voltage because is too high than 5v. The next thing i did is buy another adapter good thing i found closer to 5v which is 5.2v which is it work.....now by pda work..properly and i can charge it properly too.. well it takes sometime to look around the shop until it can be found the right adapter....

Well i used the USB to AC adapter 5.2v...it work great... for mp3 player like h320,pda........

Need to know "no bus" indicator light on instrument panel....


"No Bus" means the data cable going to the (PCM) computer is unplugged, or the PCM has failed and not able to read the information it is being given.
Sometimes just jiggling the PCM causes the ODO "NO BUS" to come on.
Sometimes a bad crank or cam sensor can cause this as well.

Here is the OFFICIAL checklist for the "NO BUS" condition....

Vehicle: 1998 - 1999 Dodge Durango 3.9L
2000 - 2001 Dodge Durango 4.7L
1998 - 2000 Dodge Durango 5.2L
1998 - 2001 Dodge Durango 5.9L



Symptom: Engine will not start. Gauges are inoperative. No BUS message displayed on odometer.



System: Body/Chassis Electrical, Emissions/PCM/Fuel, Engine Electrical



Codes: N/A



Problem 1 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Crankshaft Position (CKP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor. If 5v is not present, unplug the Crankshaft Position (CKP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the CKP sensor.



Problem 2 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Camshaft Position (CMP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the Camshaft Position (CMP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the CMP sensor.



Problem 3 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Manifold Absolute Pressure (MAP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire (5v power supply) at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the MAP sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the MAP sensor.



Problem 4 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Throttle Position Sensor (TPS).



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire (5 volt power supply) at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the TPS. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the TPS.



Problem 5 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted wire.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the throttle position sensor (TPS) or manifold absolute pressure (MAP) sensor. If 5v is not present, unplug all sensors that are connected to the 5v power supply and disconnect the PCM. Check if either 5v power supply circuit is shorted to ground using a DVOM. If the circuit is found to be shorted to ground, repair the wire and the cause of the short.



Problem 6 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Governor Pressure Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the large round connector on the driver's side of the transmission. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, remove the transmission pan and check for shorted wiring inside the transmission. If the wiring is OK, replace the Governor Pressure Sensor.


Many times the PCM simply overheats - and changing it will stop the problem.

All the modules are connected together to communicate with each other via the PCI bus. It is possible that one of the modules is pulling the bus down. If the vehicle won't start it could be any one of the modules. It will be a process of elimination to find the faulty one by disconnecting them one at a time.

Fried iRiver H10 MP3 Player 6gb due to overvoltage


Dear Buzdugan

I too once fried my Ipod mini, but got it replaced thru warranty. If u too have a warranty period then utilise it. Unless the player visually has any damage. u may even land up being lucky to get replaced with the resistor alone.

Iriver iHP-120


You can get a replecement on Ebay or at Maplins the spec is

In: 100-240V~50-60Hz 360mA
Out: 5V~2A

be careful I once fried an IHP-120 by using the wrong charger. I replaced the battery but taht wasn't the issue. I had it replaced with a IHP-140 and now my old charger has gone too. I got a replacement through the company I bought it from but they have none left.

Used the wrong charger


you should check the battery voltage first before you get it repaired.

Did he fry it?


It just had a bad current that went through it the player shouldn't fry, check the battery voltage see if its still got the original voltage if not it will be under its capacity. Rejuvenate the battery and use the right power supply this time. If its still under warranty take the player and its original charger back to where you got the player from and they might swap it out.

IRiver iHP-140


Open the player and test for battery's voltage. In case of a low voltage measurement,you should replace the battery.I don't want to be cruel with you but, maybe that the player power circuit was damaged as well,and in this case it should be repaired by a certified technician (I realy hope for you that this is not the situation). Good luck !!!
