RE: HP 45 Charger`
OK, good news here!

I replaced the capacitor, it wasn't dead but it read almost 700 uF on my meter, not sure how much that mattered.

I replaced the broken resistor, the 470 ohm one and for the time being left the 5.1 volt Zener alone for the moment. Just wanted to see if she worked. I do have a Zener in case I need it.

Good news, she worked as soon as I pushed the switch, but then after using it a few times, the it started acting up, jiggling the switch could make it work or not, so I took it apart and carefully cleaned the switch contacts. All seems well!

In fact I cleaned it up and considering it took me thru undergrad and grad school, it doesn't look bad.

Starting to think I need to build a battery for it as the original leaked and is long gone.

Thanks for all the help.

Mike
