Yet another non-functional SP-161 argon...

[Lasernerd]

OK - then yeah, it sounds like you've got a problem with the ignitor circuit (either in the head, or more likely in the PSU).

Yup. Unfortunately, I don't have schematics for that PSU. You might be able to get some help from "Weak_Station"; he logs in from time to time and is pretty familar with those small argon PSU's. Sam's Laser FAQ might have some useful info as well. But apart from that, you're probably going to be stuck troubleshooting it blind...

I started a thread in the help.
Thank you Adam for all your help,
Once the issue is found I will post complete details.

Again thanks!

On the PS 261B I have only 2 pins jumped is this correct?

[buffo]

There are two separate sets of pins that need to be jumped. So that makes 4 pins total. Have a look at the picture from my gallery above. It shows a 263 series PSU, but the remote connector pinouts are identical between the 261's and the 263's.

Could be an interlock problem or an ignitor problem. What do the 4 green lights on the PSU say? When you power it up, the standby and interlock lights should come on. Then after a 30 second delay, the lasing and regulation lights should come on. (Do you have the remote connected? Or at least, did you short the interlock pins on the remote connector?)

Adam

From your picture I have the bottom 2 pins jumped,
this supply does not have the other set of pins that your picture shows jumped?

[buffo]

Hmmm... That is strange. On mine they both need to be shorted or the thing won't light. I can't remember off the top of my head which ones are which, but if I pull either one of the jumpers, the tube won't start. I've never seen one like yours where those pins are missing like that though.

No signs of pins being inserted in the blank positions.

i cannot find any info. on the head 161B-460?

[buffo]

Don't know what the -460 denotes. Maybe something special?

I've had 4 of these lasers, and they've all been interchangeable with regard to heads and PSU's. Still, maybe you've got something unique there.

If you don't have those pins on the remote connector, then maybe the problem is within the PSU itself. But it still bugs me that your connector is different like that...

It is a very clean unit

The bottom picture is the relay that does not activate,i am pretty sure this needs to trigger to get the start pulse to the igniter in the head

[Lasernerd]

I noticed your picture is for the 263

I have the 261B like the one you have that has the controller
