I agree with LBM sir. This is what I was trying to say the whole time in this thread. Lbm sir, with the ice off I get a steady voltage of around 14.1 volt from the alternator to the battery ( checked using dmm ) with the car accessories on ( AC/ headlight/ etc but not ICE ) I get around 13.8~13.9
With ICE under heavy bass notes it dips to around 12 sometimes but is mostly around 12.7 +
Also, the problem is that it drains the battery ever so slowly it is hard to tell. I know because I measure the voltage once every day. However, I have tested my home made charger for over 2 weeks now with satisfactory results. The only problem is the spikes caused due to voltage fluctuations and the timer is not done yet. Without the timer, I have to check the battery every 30 mins or so to prevent gassing. However, if I use it for one hour each day then no problems at all, but I cannot just leave it attached to the battery overnight.
If you want, I can build you one too to check it out. pm me in case you are interested. I can do it next month sometime or you can just take mine when you come to noida and I can build one for me later |
