Yep thats the battery terminal wire. Its a common problems on these and lots of cameras from this period. The solder can fail.
Best Minolta ? Well that would depend on what you consider the best attribute to be....longevity, hipster looks, ease of use, technical prowess, heres my take on it as someone with a bad addiction to old cameras.
For tank like build and ultimate hipster looks it woukd be an SRT101 with the MC 58mm f1.4 in its day the SRT was a phenomenal sales success. The 303 is considered the peak of the SRT series but I think it looks ugly myself. Hipster el Supremo.
Ease of use probably the X700 with is program mode, its a sweet camera in many ways but the on switch does my head in. Early ones with tantalum capacitors are reliable, later ones less so but fixable easy enough. Best selling Minolta of all time so something was right about it. Nicer than Canons AE1 which it was designed to compete with. Plastic fantastic.
X570 is like an X700 but with no program mode but it does show what shutter speed is selected and what the meter wants where the X700 only shows meter suggestion. Personally I dont find that a problem and prefer minimal VF info, the OM1 suits me best with just a meter showing + 0 - as it keeps the view uncluttered.
Some people prefer the X500 over the 700 for its more ‘manual’ approach to things but to me it seems like a slugged X700.
XG series run away from these, known to be a troublesome box, best of the XGs is the XGM but later ones were bashed out in low quality in Malaysia. Trouble in store and can be serious. I have one to fix that has burnt out capacitors ...all four of the things.
XD7 or 11 my personal favourite, AP and SP modes plus full manual, sexiest looking Minolta, sleek, refined and very compact. Probably the best manual focus body of them all but never sold well in the day. Avoid any with unknown problems because they are nigh on impossible to repair for us amateurs and usually expensive for repairs. Beautifully made and if looked after very reliable (supposedly). I have two mostly bevause I cant decide which one of them to sell. One in chrome or one in black, black looks cools but silver looks more retro and better overall condition but only by a whisker. Every possible feature that Minolta could cram in with manual, ap and sp modes plus a ‘program mode’ full information VF, auto on once you lightly press the shutter, VF blind built in, exposure comp, final check metering all this plus amazing build quality....last of the well made cameras before the world turned to plastic with a disposable mentality.
XE...cant comment as I have not owned one but its HUGE and heavy like a Nikon F, its on my list to acquire once the right box comes up but you need a minter as they are prone to electronic problems as a consequence of them being bleeding edge in their day.
XM....rare and expensive if working and in good condition. El Dorado of Minoltas.
Keepers in my collection, SRT 101, X700 and a pair of XD7s.
If The house was on fire and I could take just one....the XD7
