Good evening guys .. wow it have been like 3 years since the last time I made a post in an online forum ... Facebook have eaten the whole competition you know .
Ok let's enter directly to the subject ...
First of all let me mention that I'm a mechanical engineer and not an electronic or communication engineer so excuse me if I mentioned any wrong information below.
I made a circuit (actually two) to charge a 12 V car battery (not because I don't want to buy one - but because I love electronics and this is a good chance to learn something new ) ... anyway ... This is the original circuit I made:
(see attachments for the circuit I built)
I did everything as in the drawing but only the transformer is 12v - 5 A
For the 4 diodes I bough a rectifier instead.
The output DC voltage from the rectifier is around 15 V and so from the output of the circuit. But the problem is in the current when I measure the current passes to the battery it's around 0.2 Amps only !!
I measured the amps that out from the circuit without any load and it was around 1.5 amps.
If I measured the amps out from the rectifier also before the circuit it self it is very high that I did it for few seconds only because everything becoming heated.
So I want to know why is the current is small passing through the battery ?
Also I have to mention that the battery have a hydrometer and it tells if the battery is either ... Good .. Need to be Charged ... Unusable ... (see attachments) .. It seems that it just need to be charged ? That's what made me think of charge it at first place
Thanks in advance for the help .. I wish I could post great useful posts like you does ...
