Wiring Breakthrough??

Ok,

So does doubling the cable mean more power can travel?
(IE it wont just melt one of them?)

Sorry to ask a stupid question

The Mad Hat Man · Oct 25, 2007

yup - double the cable - means each cable takes half the current each.

To add confusion,

Wheres the best place to put a battery master key switch, on a Series Landy?

Just though might be a good idea?

Best place for a power invertor to be hard wired in?

Thanks,

Thanks,

1) somewhere where it cant be easily detected, and you can supply Battery cable to and from it.

2) somewhere yu can supply a high current wire to it.

Dont forget - yu havent made any allowance fur battery cable.

84/0.30mm, 6mm2, 50amp - Typical applications. Charging cable for dynamo, alternator and ammeter circuits. But use two lengths - ie double up on the wires - yu mite want a high output alternator at some time.

Cheers mad, The question was aimed at you

What about wiring the invertor straight of the battery, then with another master key to turn that on and off, as have heard that any invertor over (either 180 or 300 cant remember which) should be hard wired in.

Anyway, had better be off for tonight, back later!

The Mad Hat Man · Oct 25, 2007

wot about moving the battery under the passenger seat, like the deependers and put the isolator and converter there too?

ffs - do I have to do everyfink round here?

my consultancy fees are quite reasonable

!!!!!!

Thanks for your help!

Hope the spredsheet helped everyone.

Will be off now,

Would you only like to use the inverter when the engine is running? If so It can be switched from the alernator with a relay, Did my auxilary electric for my caravan like this with no problems. Then if you stall you not end up with a flat battery from the inverter draining all the power.

BIOSBILL · Oct 25, 2007

Sounds like a gd idea, what kind of relay would you use?

You need to know the current draw of the inverter and work from there. I have one idea of a relay driving a starter solinoid.

Wonder what mads idea on this is?

think about it for an hour or two!! The sillynoid acts as a relay!

My thought was putting to much strain on the alternator. Do starter solinoids pull more current than a standard 4 or 5 pin relay?

The Mad Hat Man · Oct 25, 2007

The alternator dont have anything to do with the starter. that is driven straight from the battery - and yes - alot more current - just look at the thickness of the cable from the battery to the starter - 110-450 Amps or so. Yu try and find a 450 amp auto relay.

i think you should order a fire extinguisher as well as the wire

yup

iannotts · Oct 26, 2007

Ok, I will try again. What is the switching current of a stater solonoid? alot greater than a standard 30amp I would presume. So using the alernator to switch the 30amp solonoid would take the load of switching the starter solonoid off of the alernator. Then using the 30amp solonoid to switch the higher current for the starter solonoid. If not forget I mentioned the idea

Sean · Oct 26, 2007

ermmmmmm ?

make sure it's a big extinguisher

and add an auto electrics for dummies book to your order cos you is all confused about how things work

yu really dont have a clue - do ya?

best leave it to those that do - else yu can fook things big time

to borrow a phrase from grunt " wibble wibble wibble I'm a teapot"
but seriously if you take a live feed from the speedo earth and connect it through the ERG valve using 1.75mm² copper coated aluminium wire and joined using silver solder you will have a home made flux capacitor capable of handling electricle current much greater than 5.5amps per volt²km
