Red Baron 7 power points
Hello to all in the thread I'm glad to find a subject similar to what I'm working on at the moment where do the original power points connect to from the battery holders to the circuit board.Alimo88 I have the same problem or if you gave up I have yours.Or maybe just a coincidence if not.Looks like thats why a lot of red barons a sold not working,because of the twin battery packs one for the audio and the other for circuit,people replace them when they crack on the top.But because they are hard to find with the clips(original ones) not the wires people get confuse and wire snap-on clips to the wires wrong.Have I think about it .In the snap on from the board the female is positive and the male is negative.So if you put a snap-on in the battery holder to join the circuit one and follow the colors red and black again you will have female positive male negative that means you can not join them because it's the wrong polarity.But with the excitement people make the simple mistake.The easy way if you can't get the original battery holders is to disregard the snap-on clips and put a one way connector plug and while you are there put a fuse holder.If that was done there would be more Red barons around working.There is more old bounty hunter's like the discriminator-840 or raider,outlaw and so on because they use two nine volt batteries,so there is no battery holders and no problems with battery holders.So once I make sure I get the original power points like Alimo88 was asking for I can started to find out if they done any damage and start replacing.I think thanks to the great help from homefire I will solve and repair this famous old classic .Hope this has help someone before giving up.All the best to everyone on the holiday season cheers.

once I pulled it out.So after cleaning and taking apart the pot and figuring out what I could do(other than trying to look for one)nearly a miracle to find a 500 ohm linear pot with DPST dual contact switch.I took apart another pot with 500 ohms resistance and with some luck putting together some parts from one and the other I got the switch working and the mystery resistance working too.Put it together back in the board.Turned it on and music to my ears the meter was responding the battery A-and B checked good and the threshold was responding to adjustment.TR was detecting good with discrimination control also.But guess what SPD was not great and All metal hardly pick up at one inch with very low volume.
I was just about smashing it against the wall.When after a few more drinks and smoke to relax the nerves.I said one more check.All I.C'S good,all transistors and diodes good .Replaced a few 100uf capacitors for quicker response,but checking some voltages around the MC1496P that was no good and replaced.Thanks to your diagrams,it was not checking out around some resistors and the small 500 ohms blue trim pot.Resistors is very rare with the small voltage involved to give up,so I got the magnifying eye glass and testing the resistors and the trim pot.Guess what one of the outside legs in the trim pot was broken? I could not believe it how?And because it's a mystery the hands that have tried and gave up on it before me(No wonder and don't blame them).I just looked in my spare parts and found one.Replaced it checked the voltage that the schematics give you at that point with a little trim and it checked good.Now could this be it put it on All metal and it was the best sound of my life the threshold was responding the meter was responding and best of all the detecting now was working at good depths with all the items I have Coins.Gold and silver rings and nails and junk metals,from six inches to 12 inches for a one dollar silver size coin.And best of all a small half gram alluvial nugget at two inches,some detectors can't pick up that small.SPD and discrimination also was working good.So thanks to you and others for the help one way or another the Red Baron 7 is back ready to work again.With some improvements I might say,since it has like in the diagram shows a VSR control pot that gives you the ability to control the response speed,so you hardly have to move the coil or up to no movement at all (that's were it picks up the small less than a gram nuggets)Also found in the older Bounty Hunter Raider model.Homefire you have to let me know your delivery address,so I can send you a souvenir from down under.Are you able to post this in the R.B thread so I don't have to write all this again.I will be posting the final pics from the people that have taking pics of the wiring contact points.Cheers Miguel
Now I guess I'll get bored with no more to do.I'll have to ask my friend to go for a metal detecting trip after the floods we had here I guess is the best time to go over the creeks and locations where the gold might have been washed down again.Cheers to all and remember Patience.
