Harbor Freight 45 watt kit power box
« on: May 28, 2012, 10:36:06 AM »
Does anyone here have one to sell? eBay usually has a few, but I see nothing now. One of mine display died. I use two for low power taps. The 3/6/9/12 and USB taps are useful.

I usually have one or two, but even I am out.
Did the display quit? or did the little button get pushed off? I was given 3 that were this way  ;).
I usually connect them up and if NO display I go messing with the display on/off button.
Best of Luck;

Bruce, the display went 88.8. The on/off button works, but knowing the voltage from a distance is useful. The other still works.

I might get a DC volt display and fix mine if I can't find a replacement.

I may still have one.  I lost 2 in a flood last year but had 3.  I will check and get back to you.

I bought 2 of these from eBay to attempt a repair for the display. Two wire hookup.

http://www.ebay.com/itm/Mini-Blue-LED-Digital-Volt-Meter-4-5-30V-For-9V-12V-24V?item=390341332475&cmd=ViewItem&_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D3%26po%3DLVI%26ps%3D63%26clkid%3D8854082818245703770

$10 including shipping. The seller says they are reverse. All the really cheap ones carry warnings not to hook them up backwards. Since the HF boxes have battery clips, that's possible. To add a diode inline would change the voltage at the meter. Some others forbid using the source for supplying the display. I'll let you all know how this goes.
