1-Volt battery drain?

[David Nock (RIP)]

As an old geezer, with absolutely no experience of FD\'s, can I stick my neck out and say that if the headlights don\'t dim whilst cranking over, it\'s not likely to be a battery problem as the battery voltage seems to be holding up. Anybody correct me?

David regarding your point I would intially agree, but why would a jump start or a fully charged battery start the FD? Perhaps, the Cold Cranking Amps (sp) CCA value is too low - from memory its 550 i think.

Hmm..... well I know you have to get rotaries spinning fairly fast to start them, so you may well need a high value of cold cranking amps. What if your compressions are down Ash, or what if something in the electronics requires extra high battery voltage on ignition? I just don\'t know mate.
I do know that the FB has to be run fairly regularly if it is to start easily. If it\'s left if cold weather for say a week or more it can be tricky to start, even though it will then go 1st time the next day. No bearing on your problem though?

I have checked the CCA and its 565 and 65ah. Voltage is down to 12.39volts. I reckon Im going to have to bite the bullet, but I will also see if topping up with distilled water makes any difference?

Anyone recommend a really good battery in case?

find someone with another rex that works, and try their battery lol! if i was closer would let u try mine but im not lol sorry

Malice - good idea, anyone near the Watford, Herts area that could pop over sometime? Will cover petrol if not too far.

Today I got a jump start from a \'Power Pack\' one that gets its power from the mains and the car fired to life so quickly its was amazing :wiggle - so Im going to bite the bullet and go for a high powered battery with a high Cranking capacity - can someone recommend a decent battery please, the higher the CCA the better i reckon - no £150 + batteries though, it is Xmas :yes
