1541-2 issue

hi i wonder if anyone out there can help...

i seem to have a problem with my 1541-2 drive....this doesnt happen all the time but it is getting more frequent and becoming a problem...

when i 1st switch my c64 on and then my floppy drive the drive light comes on and the head starts spinning and both keep going and going and going....eventually after alot of powering off and on the drive starts as it should do...

does anyone know why this drive might be doing this and how to fix this issue

thanks

exactly what does this mean???

"1. Cut the cable of the 1541-II power supply by the side of the brick." - does this mean just cut the cable from the psu that goes into the 1541-2?? if it does then i should be able to make this no problem at all....

i take it i only need to keep the cable side that fits into the back of the 1541-2...the rest can go in the bin yes??

Instead of PC power supply you can use a "switch mode" power supply with 5/12V output. I'm using the one came with my external 3,5" harddisk enclosure. Something like this:

now this is getting interesting...

impetigo did you just solder the wires from the 1541-2 cable directly to the pins of the switching cable??

Actually I bought a female connector to connect the power supply. I soldered this (female) connector to the 1541 cable. Then I simply connect them together.

But if you want you can cut the connector of the power supply and solder your 1541 cable to the power supply cable. Cos' soldering to the pins of the connector is gonna be really difficult.

Also, don't forget to double (maybe triple) check your work. You wouldn't want to mix 5V, 12V and GND lines.

Good luck.
