Re: Leni conversion #3


 

WAIT!

I forgot first step-- important. There is a 1/4" hex head going through the PCB near the transformer, that one screw is the only one that grounds the PCB to the case. If that is not there, it won't work. Also check PCB VERY closely around that screw, because of the weight of the transformer that large conductor trace that the transformer is soldered to can crack, separating the ground connector from the back of the PCB to the front of the PCB where the meter is.



Next step after all this is change the HV diode and the two electrolytic capacitors.

Subject: Re: [CDV700CLUB] Leni conversion #3

got around to pulling the ENI I got off epay out of the box and checking it out.? A problem child - but it is an ENI.? Could use suggestions from the smart people in the room -? the ENI turns on but doesn't do anything. Turn it X10, the needle goes right to about 2 mR/s and sits there.? Turn it to X1, it goes full right.? You can move the needle around with the calibration knob on the ceramic component module (MOD A).? There is no sound. No clicky.? and no response to the check source. You just turn it on and the needle moves to position depending on the range setting.? ?From what I can tell, this ENI seems original - no evidence of any previous soldering.? ?

I suppose I should start with the basic checks outlined in the manual.??
