Altenator charge under load

[Red Westie]

Interesting toys Kev....definately a useful guide to let you know when things are going flat, charging and have reached fully charged condition.
The is always a but .....but going on those numbers definately just a guide (just a 16amp draw showing when cranking)....surely there is an extra zero on the end of the sixteen? lol or is the ameter isolated from the starter battery?

Also what is the white dial on the right, is that cabin pressure?

Read the WIKI bit and I am gussing something wrong with my Alternator. I done investigation today.

I got a Holdsworth 1984. I inspected my Alternator today. There are no markings on it or a label, all worn off. It looks fairly used, so guessing it’s a 45 AMP version.

Anyway started up here is my voltage readings

Battery
12.6v - engine off
13.7v - Engine running; no load
13.1v – Lights on
12.7v – Lights, Fan Blower & wipers

Shouldn’t the voltage be higher then that under load?

Mine reads the same with a 6 month old regulator, but I've never had any problems with starting or running the leisure battery, and when we camp I have the stereo on for about 8-10 hours a day from the leisure

OK, maybe it is ok then!

he he ...No it's oil pressure at the tappets... and the larger one is interior temp, sad innit

Not sure where it's taking the amperage from Martin, suffice to say the cabling is quite substantial and those readings are from what I witness.
I does show all the batteries recharging but only the starter batt when the key is turned.
