CUR showing on the display

I am facing a problem with the current. in the manual it says if CUR appears its high current flow problem. but i cant find the problem. the amp appears normal when the sub output from the player is off. whn i switch it on only a bas comes and the CUR starts flashing. what can i do abt this am curious.. i am using Pioneer TS-W101SPL 600 RMS (dual 4 ohm connected in parralel) it seems both my amplifier and sub is ok.. plz help me out wth this :)

Have you measured the DC resistance of the woofer to determine if it's OK? You will need to disconnect it from the amp. Check each voice coil individually.

 

If you disconnect both speaker wires from the amp, does it still show an overcurrent condition?

Water won't drain


Do the diagnostic test:
SHU 53 MODELS

To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ ?21? = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show “88′ when REGULAR WASH button is pressed and “8h” when Delay Start button is pressed.
To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ ?6? = faults 2 + 4).
0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault
1 = Aqua Sensor (“Sensotronic”) fault 4 = Filling fault F = Filling fault (display occurs during wash, not test)
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), display will show fault code “4′ and unit will continually fill and drain where testing won’t be completed. If flow switch (e5) has failed (opened), display will show “0′, water won’t heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code “8′ immediately and testing will end shortly after water has started circulating.

The dishwasher not draining is most probably faulty drain pump or drain hose is got bit loose.It has to be checked and confirmed

My mrv f345 amp reads CUR on display screen and has no sound.


That error appears usually when the speakers (especially subs) aren't getting the current they need from the system. Check your wiring and make sure you're using the appropriate gauge wire. Too small of a gauge in wire can cause this.

Amplifier displays "CUR"


Hello anwbrown,

The "CUR" display means that the amp is drawing excessive current and the protection circuit is activating. Too low impedance or shorted speakers will cause the amp to draw excessive current.

The Alpine V12 is a Class D mono amp with only one set of speaker outputs. All versions, M301, M501, and M1001 are only stable to 2ohms. Assuming that all 6 of your connected subwoofers and speakers are 4ohm and they're all connected in parallel, the amp sees a .67 ohm load, far below it's rated impedance.

When brand new, the amp could probably operate at low to moderate volume levels without drawing excessive current. But as electronic components age, their tolerances change and they become less able to withstand excessive current or mismatched impedances.

I'd get a 4-channel amp and drive the 4" speakers off the front channels and the 6X9's off the rear channels. And just power the subs off the V12 making sure that they are connected to show a minimum load of 2ohms.

Hope this helps.

How do you get it out of cur mode


Hello whatup_132,

If the M605 fails and displays "CUR", it means that there is excessive current to the amp.

The most common causes for excessive current draw is operating the amp into a lower impedance than it is rated to handle, shorted speaker voice coil(s), and/or shorted or grounded speaker wires.

The amp can operate into a load no lower than 2ohms. First power everything off and disconnect the positive amp power lead temporarily (easist way is to just pull the fuse). At this point you should ONLY have the ground and remote connected. Reconnect positive (insert fuse) and turn on the vehicle ignition and your head unit. If the amp still displays the "CUR" error, the output MOSFET's are probably defective and the amp requires repair or replacement. If it powers up normally, reconnect the speaker wires until you locate the faulty one, and then correct whatever is causing it.

Hope this helps.

CUR display


Hello yte1771,

You can download the manual from Crutchfield.

The "CUR" display is an indication of excessive current and is most likely caused by too low impedance or a fault in the wiring or the amp itself. It's probably not your cap.

Hope this helps.

CUR is showing on the display


The amp will reset when you cut the power off to it. Disconect bat for 30 sec and reconect. But to be honist with u if the wire jumped out and grounded some how during a high level, there is probley internal damage done.
