Projecta Battery Charger problem.

[nickyminaj]

Hi,

After having tidied up the electrics in the front boot of the van and finally fitting the charger to the 120AH deep cycle Glass Mat battery,the charger,having previously not missed a beat for 5years will not get past 00volts on the gauge. Followed all instructions in the manual …no change,no codes or signals emitted but 00Volts on the gauge . I tried it on one of my car batteries to no avail.
It is a 25A 7 stage Projecta and battery is in tip top nick. There is no evidence of a fuse accessible on the exterior?

Any idea?

Please help.
Thanks!

I didn't find the right solution from the Internet.

Is it the problem by charger or battery?
