Hi everyone, new here.
The fuses recently went on the battery charger/starter i use. While it was apart decided a general overhaul would be a good idea as its quite old (20+ years). This was when i found out previously some of the diodes had blown and it had been made into a half bridge as opposed to full bridge rectification.
So, I'm trying to find some replacement diodes. IT is a large 12/24 volt capcpale of 80 Amps plus. The current ones are DO-8 package i think. I've never encountered diodes of this size before. There are two sets one for the 12V tap and one for the 24V tap off the transformer.
I've been looking on RS/digikey etc, I can find diodes with a suitable amperage but the rated voltages are all very high and very expensive £40+ each. Am i right in thinking that as they are after the transformer the voltage rating doesnt need to be in the hundred just a safe margin above the peak voltage at 24VAC?
Can anyone help point something suitable out or are the expensive ones i've seen the ones that are required and they are just an expensive part?
Cheers
Sam
