Reaper is right it's sounds like a short there.

The two wires are touching somewhere to make the battery get hot, smoke and flames.

I use NiCad, NiMH and Li-Po batties in my PR and it works fine.

It could be were the wires come out of the back-top of M1A1 near the stock and goes around the PR through the carry handle and down into the S.P.A.S cage were the standard stick battery would go.

The easy way to test the wire is a tester unit. Put the tester into connection mode and put one probe on + and the other on - in the block connetor were the battery plugs into. If nothing happens than it's not a short and plus you can make sure the trigger working also by pressing the trigger.

If you can a short I would take the shrouds off and have a close look at the wiring but you will noitce black marks on the wires.

Cheer's Steve

yeah i saw that on PVB website, ive looked into the gun and it seem the T shaped thing is fitted the correct way

No worries mate. Just thought it was worth checking. Hope you get to the bottom of the short problem one way or the other. That's a good bit of improvisation that Reaper mentions.

Cheers.

John.

Haha! probs best.

Send it to me to look at...... might get "lost in the post" mind you..... Hahaha!

Haha! Thanks John, I've made a few circuits held together with blu-tac and duct tape in my time

Solder is for wusses!

Ok so i get a battery to see of the PR works (its a G/P kit with a TM thompson ) it works just fine until smoke starts pouring out, i quickly removed the battery and it the bursts into flames what would cause that?

Wrong voltage perhaps? Or just a dodgey battery? Could also be a short in the gun.

Was 8.4 v though was a very tight squeeze to get it in but did not think the voltage was that important I've read of people using higher

I'm guessing there's a short somewhere. Is it a Lithium Polymer battery? If there's a short then they tend to smoke and catch fire eventually. Perhaps when you inserted it you stripped a bit of cable and caused a short?

Everything seemed fine it was 8.4 1500 mAh 2/3A NiMH stick now i will be honest i dont know much about this sort of thing only know what ive read and i am not personaly going to use it to fire i just wanted to know it all worked ok should i want to sell, but im sure even with my limited knowledge flaming batteries is not right

I can't think of anything else it could of been, I'm no expert mind but I've witnessed shorting batteries doing the same thing. Have a look at the wires coming out of the gun and see if there's any metal showing, if there is then whack a bit of tape around it and try it out.

all the wires i can see are just fine, im thinking maybe its because i had to force the battery in but i dont know maybe one of the experts will be on later

Cheer's Steve Thanks steve but i have no idea what all that meant if you have one of these tester things bring it to LFCC and i will let you show me what your saying lol

Sounds like Data is talking about a continuity tester. It could be a short in the battery which would probably mean buying a new pack but I'd say go with Data's idea of a wiring test first to save you potentially frying another pack. If you get to the point of having tested the wiring in the gun & trying out a new battery pack I'd lay the gun flat on its right side, then connect the battery without fitting it into the launcher cage. You can then disconnect the battery quickly if there's any sign of a short whilst testing the gearbox. I'm a bit puzzled that you found the battery a tight fit in the gun though. I use the same 8.4v 'stick' type & battery changes are no trouble. I'm wondering if the T shaped piece that the pump grip mounts onto has been fitted the wrong way round? See the 5th image down on page 10 of PVB's guide. You should be able to check with a torch whether it's correct or not:- http://www.medwaypvb.pwp.blueyonder.co.uk/pulse10.html Hope that's a little bit more help. John.

If you have a working AA/AAA battery, a couple of bits of wire and a loose LED bulb or even a bulb out of a torch then you can make a basic version of the tester Data mentions. Basically get one piece of wire and tape it to the negative end of the battery. Now tape another piece of wire to the positive end. Now tape the other end of the postive wire to the (LED:) long stem (Bulb:) Base. Next tape another bit of wire to (LED:) short stem (Bulb:) metal casing. Finally conect the wire from the negative end of the battery to the negative (black) prong in the P-Rifle battery connector, and now with the trigger pulled, touch the end of the positive (red) prong with the wire coming from the metal casing of the bulb. If it lights without flickering or blowing the battery up then there's no short. 1. I hope that all makes sence! 2. I hope it's not patronising for you, I'm not the best teacher! In essence; make a basic circuit and use the trigger on the rifle as a switch

Haha! Good stuff, I normally pull off a 'Now children...' kinda vibe when I explain things so I always like to applogise just incase Anyway, Another way of seeing if there's a short is to take the PR apart and look for any burnt bits on the wires. If you can't see any then go on YouTube and find one of the thousands of vids explaining how to take a TM Thompson apart, then look for any burnt bits in there. You don't need to take the gearbox apart I'm pretty sure so you won't void te warranty or anything Simply trapping a wire in the housing can cause a short (which is where two wires touch and basically makes a circuit that connects both terminals of the battery to each other instead of going through the motor/light etc (I.e making the circuit shorter, hence the name), which isn't good as you well know!) Like I said I'm no expert but what I know might help you out Haha! Thanks John, I've made a few circuits held together with blu-tac and duct tape in my time Solder is for wusses!

LOL! Point taken. Served 16 years in the TA myself but still have a keen interest in target shooting. Airsoft is a bit of a 'sideline' which some friends pursuaded me to try some years ago. Good fun & not to be taken too seriously. Hope you get the PR fixed without too much trouble, even if you have to wait a while to get it done. All the best. John.

Appologies for being off topic but this getting weird now: Ive been thinking about joining the TA for a few weeks now and today not only have I seen 3 squaddies walking down the road, my TV freezes on the advert right at the end where it displays all the contact info, I check my emails and there's not only one from my buddy in the paras but one off the recruitment people and now I find out you two are ex-army too!! Someones trying to tell me something I think.....
