Does anyone have any information on this 30 Amp (15A + 15A) battery charger?
The unit I have appears to go into "crowbar mode when any load is applied.
Output into VOM is 13.8 Volts but a 20milliamp globe across the output drops the voltage to under 3 Volts. The manufacturers in their wisdom have ground off the type names of the I/C's in the control circuitry so normal substitution is not possible. As a retired technical officer I would happily repair this unit myself if I could get some data or a circuit diagram of its internals.

Hi Mal C1,
As a suggestion try putting the model No. into Google, it comes up with a page of possibles under different names and maybe a circuit in there somewhere.

Good luck. Jerry

Tried that could only get manufacturers advertising spin and charging data - no diagrams- thanks for the suggestion.

G'day Mal C1 - I didn't find the 30 amp model, but here's all the technical info on the 20 amp model, if that's any assistance.

Thanks Ron, my unit is diffferent internally from the data you sent to me, but your info will be a great help in nutting out a possible solution.

Recycling bin is the best place. Well known for failing.

Hi P2D2, you are probably correct but I never chuck ANYTHING out until all else fails,

You could be dumping your batteries as well because usually when the fail they fail in full boost mode and wreck your batteries. We have pulled out heaps that have failed.
Good replacement is the Projecta IC series Intellicharge

Mal,
hope you find the bits you need. I have had a good run with the same charger as you except it is 15amp.

I leave it on the bullbar run by a time clock and plugged into a socket behind my indicator light. Three times I have backed out of the shed with it attached. (you would think I would learn after the first time).

On all occasions it has hit the concrete and on one occasion I dragged it about 20m to the street. It is still working fine and has been in constant use for approximately 4 years. Last week I bought my van battery back up with it from 11.5 volts after a power point was somehow turned off in a cupboard.

Happy repairing,
RA.
