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

I experienced the same issue because of PSU. |

I had kind of similar problems and discovered that the PSU gave more than 6V instead of 5V. I got a new PSU and now it works fine. Interesting that not all 1541-II behaved the same with the faulty PSU, some of them worked fine.
I built my own heavy duty PSU for both C64 and 1541-II, based on a transformer + switching regulator + overvoltage protection in case of failure. I will eventually provide these PSUs in kit after this summer I hope,my prototype:

I can't. I could supply you with a PSU kit once it is ready, but you have to solder the parts yourself. This is because for selling a PSU, a certification is required and that costs a lot, which would make the single PSU unit unaffordable.
Most likely the kits will be a bunch of components to be soldered on a board (already drilled and with all the traces). and of course detailed instruction on how to proceed with the soldering.
Let's see what I can come up with this summer.

yeah a pc psu is definately the way to go, when mine packed up i just chopped off the 1541 side of the power lead (at the power supply/brick end of course!) and tacked on a PC hard drive power socket. this way if the pc psu ever dies, you can just unplug the lead from it and plug it into another one.
I used a non atx PSU that i had lying around, cos all those years ago i couldnt work out how to switch an atx supply on without having the motherboard present :) the drives being supplied with this (a mkII and a cmd) are happily rocking to this day, approaching 10 years now with the same psu. |

I had exactly the same issue with my 1541-II and it was because of the original PSU. I use a PC PSU now and my 1541-II works completely fine.

actually paying somebody for selling a completely built non certifiede PSU is legally not so safe. In case somebody gets hurt, complications might occur. Furthermore transformer based PSUs are much safer for te hobbist to fix and mess with.
