I want to install the isolator as the car sits for long periods and the radio, alarm etc slowly drain the battery, so I want to fit the hand screw type isolator BUT it's designed for the -ive post and there isn't enough room under the bonnet for it so I want to ream the clamp out a bit and put it on the +ive. (plenty of room for it)
Can anyone think of why this would be a problem. The actual bolt that the current would travel through is at least 10mm thick.
Any ideas?
Thanks Slammin

Does your radio require a security pin each time it's disconnected from the battery?
This would prove to be a major PITA.
If the battery is in good nick, it should survive months of "non use".
The amount of drain from a radio not being used and an alarm system, would be negligible. If the battery is not holding a charge, the chances are it's cactus and even isolating it, won't do anything positive.

Funny you should mention that....
It's a brand new battery. And the alternator is fine.
Thing is though we have no need for a car here so yep it will sit for a few months at a time. I also like the idea of it being a quick emergency disconnection. Probably never need it but cheap reassurance anyway.
Theft is a not an issue for once!
Thanks, Slammin.

Only other minor issue is with being off for that long and seldom used, the EFI if fitted would be constantly in "learn" mode leading to poor fuel economy.
The other minor issue is that the fuel would be of the wrong seasonal blend when you did use it leading to potential poor running. Not to mention internal corrosion, and other general maladies of vehicles that are rarely used.
If you really don't use the vehicle more than 3-4 times a year, is it worth the rego ($550) + insurance ($500?) to keep it, or could you use other means of transport. $1000 gets you a long way in a taxi, and supports a "local" industry.

We're in a fairly remote location so no car is not an option (to get a taxi to come is $650 LOL) and the car usually does at least 20,000k per annum regardless.
Your point about the EFI in learn mode is interesting, does it go into learn after power disconnection or is it after a period of non use. Theres not much I can do about it ether way but it's always interesting for me to learn more. TOO

Learn mode is usually after disconnection for a period of time, even overnight will do it.

Think laterally! Purchase a small solar cell – up to 5W. Mount it on your carport/garage and run a piece of figure '8' flex down and have enough length to reach the car. You have a couple of options from there one is to terminate it in clips that so you can connect it to your battery and the other is to wire it to your battery with a plug & socket close to the battery (this way even your wife can connect it.) This will cost a couple of shekels more but you will not have to restore your radio codes, clock etc when you return.
I mounted a DSE 5W panel on a frame made of heavy timber so it would not blow off the roof in windy weather. I used a polarised 2 pin plug on the end of the figure '8' lead (looks like a 3 pin 240V job) to mate with the output socket on the outside of the caravan. I mounted a similar socked under the bonnet of the wifes Corona. The panel sat on the van when we were
home (no power in the compound) and on the carport roof while we were away. Kept both batteries alive.

If you have two vehicles, why not swap around occasionaly so that the 4by is not sitting there with possible condensation in the diffs, water siting around all your door rubbers, dry start ups because the oil has had months to drain to the sump, your wheel bearings dont get pit marks in them, and your exhaust system rusts out due to starting once every 3 months for 15 mins and condensation is caught up in the muffler and engine pipes, Just a thought might save you a lot of $$$ in the future, Regards Steve M
