12/24 volt battery charger
Dear Resqueline,
thanks for taking the time to look at this horrible setup,I bought this charger 2yrs ago, it is out of warranty now, it did charge 3 batteries, it has a boost start feature for flat batteries on any 12/24 volt vehicle,but this was never used. when i last used it i noticed that the transformer had developed a high pitch hum,then 30 secs later, bang capacitor up in smoke, I traced back to the centrer tap transformer, no wireing faults, but tested 6 button diodes and found two of them faulty and the insulating melted, i tried to buy same in the UK.but no luck, I got 10 from the US on ebay 4 day delivery, I used 2 new and 4 old to see what might happen i made a new cooling alloy plate and fixed the diodes firmly to the alloy plate,replaced an old cap from a, TV switched charger on ,90 seconds Bang cap gone, It then struck me that a forum member suggested cap may be in wrong polarity, so i had one cap left 25v 1000uf the original was 35v 1000uf, stand clear, yes we have lift off, just charged a big tractor battery from flat, transformer quite and cool, diode alloy plate very warm, battery fully charged,green led says so, also tested with volt meter batt volts 13.9 good, will it last or should i convert to
your full Bridge Rectifier, Thanks again. Dullspark.
