Electrical question about wiring and timers :-)
muddyjames:
Cheers guys.
I have now completed my wiring and installing. The light isnt as bright as I thought it was going to be but with a 8w light that should be coming soon that will go in the centre of the roof in the boot, which will be instead of the poxy little light that is supposed to come on when you open the door, it should be nice and light in there for if i need to dig around and find something.
I have placed the 16w light on the bit of plastic in between the alpine light and the back window. It fitted perfectly mounted under there.
I have wired it into the constant 12v for the towing electrics. I hope to get a 12s socket and mount it in the back door sometime but not bought the socket yet. I have a spare in my caravan that is 2 hours away from me!
Mental note though. Dont forget to leave it on!!!

I could be a smart arse and work out how long it will take to flatten your battery, but how about I suggest some sort of foolproof switching system that will prevent such an error from happening?

When you want to calculate energy its simple to draw a triangle and then draw a T inside the triangle, giving you one section at the top and two sections below. Then write a W in the top section, then A in the lower left and V in the lower right.
When you need to find out problems like the one in this topic you substitute W for Watts, V for Volts and A for Amps. Then look at the figures you have like a maths question i.e. W/V = A (24w/12v = 2A)
Using this simple tool you can calculate fuse rating, current draw etc.
HTH :wink:

I am thinking about trying to buy a timer so it only stays on for 5 minutes for example like the interior lights on the disco already do.

this triangle is really useful as I got taught it at school. I can just never remember which letter goes in which part of the triangle :oops: :roll:
