IrfanParticipant
Whoops sorry, in the above diagram VR1 is 100K and not 200K.
IrfanParticipantwysiwyg_imageupload:10104:height=532,width=750some modifications that I did to no excellent luck are demonstrated
IrfanParticipanthey good morning Pete, I havent had any luck on this yet, kindly lemme know if you have met Ms Success
IrfanParticipantHey Pete, best of luck, I await thy response, and yes I did search for you online but got a lot of nice music but no mail ids for you, and I sure do hope what you build solves thgis long running mystery
IrfanParticipantHey Pete thanks for all your efforts, this aint yet worked for me, so waiting for whats coming up, anyways searched for you on net and downloaded a lot of your music but could not find any contact info like a mail address
IrfanParticipantDear Pete , lady luck sure aint happy with me, this is what I have made, tested and failed, somehow am just doubtful on the preset value, shouldnt it be lower rather than so high, please lemme know if you have been able to make and implement tthis circuitwysiwyg_imageupload:10057:height=700,width=700
IrfanParticipantSob Sob, Pete tried everything you had guided, changed zener to 10V and then 13V and also R4 to 5K Vario, but alas seems lady luck aint happy with me at all, now if I connect the 10V zener voltage drops down to 11.96, and with the 13V zener nothing happens, if I change the preset(adjust) then nothing for 13v zener but in 10V zener fluctuates only a bit from 11.88 to 11.96, which I guess is not suffice. What do I do now and is there any other way to contact you via mail or somethng
IrfanParticipantHi Pete, have tried pout this circuit and sob sob sob sob, it doesnt work, I have made it exactly the way you denoted but the RED Led comes on and cuts off the charging, the charger voltage is set to 13.8v without the zener connected, and the moment the zener is connected it drops off!!!! what do I do now, also the funny part that I noticed is if the zener is not connected and I touch it with my finger the RED Led comes on and stops charging, funny but true, so what is it that you can please help me with now, the circuit for sure did look very promising but hasnt yet worked, also some points I would like to tell you the batter used was a AMPTEK 12V7.6 SLA and transformer was 18-0-18 1.5 Amp, the battery post discharge showed voltage as 12.42 and on full charge generally shows around 13.10. Please guide your help is utmost required.
IrfanParticipantThanks for your circuit Pete, I shall be implementing the same shortly and updating you accordingly, I am sure this will work, but again wish to check it
IrfanParticipanthey Pete thanks for your response and the corrections, I shall be implementing this circuit shortly and update on the functionality, I just hope that it trips the way I want it to.Thanks again
IrfanParticipantHi & thanks for the response, in the circuit provided by you I do not understand the negative bus, kindly guide, I shall be building this circuit shortly
IrfanParticipantThanks for the response, Please guide as to where the negative bus is running and I intent to be usig a 18-0-18 transformer for the 12V7.6Ah SLA battery, in the above circuit the negative bus is not very clear to me.<br> I shall be building this in the coming week starting from scratch and since this is a busy week of festivities may be delayed, however I appreciate your efforts and promise to update you on the status of the circuit.
IrfanParticipantI have not yet been able to solve this freaking issue, all i seek is an auto cut off charger
IrfanParticipantThanks for the response
Volatge is
Before diode 14.95 & 14.65 after diode
Please be updated that all diodes used are 5402 & not 4107
