Do you have an alternator or dynamo? Check the belt is in good condition and not slipping?
If the battery light is on your probably not getting a charge back from your alt/dynamo, do your lights dim/bright with engine revs?

WHS ^^ - sounds like charging the battery from the alternator is the cause, get a voltmeter on the alternator/dynamo and see if it's sending the correct voltage back to the battery to charge - on the bright side you probably have a spare battery now 
I'd put it on charge and have it on standby,
On the alarm front, the usage should be minimal - so you'd expect the alarm to draw say, 0.2A - on an 80 amp hour battery that can supply 1 amp for 80 hours, that would be roughly 4 times that - could always disconnect it to see, but it does sound like you bus isn't charging the battery when going along, further highlighted by the red light - hope that helps

im not sure about the lights tbh mate... im not sure if i have a altnator/dynamo.. how do i check as i say its my first bus so ive got a million and one things to learn.. do you haveany idea how much is volts it should be sendin back? i binned the old battery because the AA man said it was shot, is it a massive job stickin a new alternator on? i dint think it was the alarm but was worth a try and the red light spells danger.. thankyou guys! ps the belt is fine! cheers again wires
Stick the multi meter across battery terminals should be about 12.5 volts start engine and increase revs should go to about 14.5, if you turn the headlights on should drop then go back up when you increase revs.

that noise you speak off fella, you may wish to get under the o/s rerar of your bus , taking with u a torch and ,ensuring your bus is not in gear locate starter motor and whilst your pal operates the ign. key ,look and listen, you may also put your finger against solonoid and feel for any "chattering " and , check ,physically the condition of all ! the wires ,i.e. grab hold of them ,they should be clean and tight your starter could perhaps be worn and/or simply need a clean out along with solinoid, there are a few ways to eliminate a prob , one is keep replacing parts till you replace the faulty one(expensive!!) the other is finding the faulty part by inspection /testing , i know which i prefer !batteries cannot make noise with exception of exploding (rare), these vehicles are cleverly designed with a view to ease of repair , take your time, test each part of system in turn i.e. brushes in alternator /dynamo is a common source of basic elec probs and cost approx|£4 to replace yourself >hope this helps you, if not ,post again, and if you find the fault ,let us know please?
Evening guys... sorry for a slow reply on the matter.. i have still not got under the bus... i shall be under her soon to try and find this fault as its cummin upto summer and i want the bus out even more... im pritty sure i shall be gettin stuck so may need more help and advise but im new into this... i shall let you no my outcome and get back to you. thanks for the replys guys! wires
