Battery....cranking Speed

[DoctorDee]

Apologies for the delay in replying.....been a busy week at the place wot helps pay for my little hobby which usually means long hours.....Got my hands on a 550 CCA battery, almost new, lying around in my sons garage. Children can be useful sometimes.....borrowed on the basis that if it was OK then I bought it.

 

First problem....bigger...second problem....polarity opposite way around....

 

Out with the grinder.....butchered the battery tray cover....room to insert battery and change terminals over.....had to fabricate a bracket to hold the pressure bottle for the cooling system....

 

Crossed fingers...turned the ignition key.....engine cranked like a looney and fired....

 

Only half a tale of course.....

 

Out with the amp clamp.....clipped it on the positive lead just this side of the battery set to 20 amp....dial showed 0.01 with nothing turned on....

 

So I have a parasitic drain but is that reading significant???....

KISS

If you cant find where the drain is, just fit an immobiliser key

& shut off everything when she's all tucked up in the garage.

Amp clamp may not be accurate -- disconnect one side of battery & connect a very low wattage tungsten lamp in the gap ( in series) any glow will prove leakage 'cause what you are showing on meter is only 0.12 watt.

Or have a intelligent charger connected when car is idle.

Have an immobilser fitted which I am now using......However I would still like to find the problem....If I have one that is

[DoctorDee]

Sorry Florin....will do as you suggest

I wouldn't worry about a 0.01amp drain. Not enough to make a difference even if you don't drive it for a month.

Plus 1 for nicko. I had a similar issue where my battery voltage was fine, as were all of my earths. I had slow cranking or non-existent starter action on my pinto. I suspected the battery but ended up replacing the starter motor. It all works perfectly now.
