Shocker 9V

[jackmilehigh]

Ive heard you can run a shocker off a 9V battery. Can anyone tell me

1) If it will fry my 1999 Dome switch board?

2) Roughly how many shots will I get per 9V?

3) Ive got a spare dead battery. Can I cut the leads off and just soldier on a 9V socket? and

4) Which wire goes to which terminal?

Any help is greatly appreciated

yes you can do it Planet sell the 9v conversion lead

1) No, but has been known to happen so don't use a "fresh" High output 9v (Smart Parts don't like it but then they are/will lose battery sales) The Smart Parts battery output is lower than 9v but then so are used (old hopper batterys ?)

2) Not a clue

3) Yes you could 'cos thats how everyone first started to do it before Planet made/sold one

4) the Connections are Black - and Red + from the board and looking at the Planet connector so work out from the battery pack if they are different (haven't looked in my Shocker)

BTW I have the Planet connector but haven't used it only 'cos I had enough spare batterys when I bought it so just hasn't been used.

Thanks Mark. Im thinking of doing the same thing and sticking to the normal batteries. Jack

Find out what voltage needs to go to the board(8.4v i think) then go to your local electrical shop and buy a 8.4VDC regulator and fin that in between your battery and board...then there is no possiblity of burning your board and it will give you a little buffer energy.

9V will not fry the board, i have one of the oldest 4x4 shockers going (No 1078) and have been using RECHARGABLE batteries since i brought it in 1998 and have never had a problem.

most rechargable batteries run at about 8v or so if you also put a on/off between the battery and the board this will cause a drop of about 1v meaning you are running at about 7v or so, which is about the same as the smart parts battery packs.

RS components have all the parts you need, you just need a little skill with a soldering iron.

Or i can fit you a on/off switch and battery connector for a small fee

cheers

Ok, or you can change the on/off for a LM317 3-terminal voltage regulator and set the voltage anywhere from 1.2v to 37v which can set the load as accuratly as 0·1%

They are also useful in warp feeds when making a 12v battery pack, then you can put it back down to 9v

Guys Guys calm down A 9v will fry the board if it IS a 9v output thats why I said use batterys that are little off their best, step down resistors etc aren't needed if you use oldish batterys (or even cheap...£1 shop or "Buck or Two" store types). A rechargable battery as already stated isn't actually a 9v output, Also the resitor inline on the Planet on/off (primarly for the LED) drops the voltage approx 1.4v so together with a Smart Parts battery with an output of 8.4v means only 7v is getting to the board. The Planet connector is made using the RS components 9v connector (hard plastic) so if you do decide to use a old Smart Parts battery lead and a connector DON'T use the flimsy clips that you used to be able to get from Tandy (Radio Shack) cos in time you will screw it up.

Mark, i said to do that if it is a 9v that way the battery will last longer without frying the board.

 

[Mark]

Phillip I know you did but then all you and Bruce jumped in with the voltages etc as well was repeat in deeper terms what I had already said. remember the most basic principle in all design and manufacturing K.I.S.S. don't need to translate that do I?

Aaahhh....i see

I dont like keeping things simple...i need to keep this constant voice in my head occupied...
