    Not trying to get off the topic but If you were to weld to the frame of the welder, would it damage the battery or voltage regulator? I bought a Bobcat 225 lp welded a D ring on the handle at previous owners suggestion, used it a few times after with no issues, now it won't charge and I have jumped it with jump pack...what's the most likely culprit battery or vr? Some will say have the battery checked, yeah nice thought but its a real B*+#% to get to with the Lp bracket mount...
    Quite likely that you have blown the Voltage Regulator....
    They are VERY FRAGILE
    Typically they will charge when running... then drain overnite and have a flat battery after several hours...
    there is a Zener Diode buried in the epoxy potting of the Regulator Pak... that is the usual culprit... and it is non-repairable....

    easy way to test is to disconnect the battery... charge it up.. and let it sit overnight or over weekend... then reconnect and see if it will spin the engine... if it still has the charge... likely the reg.... if it went flat while out of circuit... then probably the batt...

    If it is the Battery... easiest answer is Wally World and pick up a "Group #58" battery in the automotive section...... for about $50..

      Do not Jumpstart either Bobcat or Trailblazer... nothing good will come from it
      Here is another thread on it

      and from yet another thread on SFT

      Thank you for your inquiry
      Miller Electric recommends you disconnect the battery. Charge the Battery
      and then reconnect the battery. Never jump start your Trailblazer, PC board
      damage is possible.
      If you would like to discuss this issue further please feel free to call us.

        I'm going to ask again. If you jump start a bobcat from a truck battery and have the truck turned off seems like that would be ok.

            I've jump started my Lincoln Ranger from my truck & I've jump started my truck from my Lincoln Ranger before with No apparent damage to either that I've ever noticed .

              What about using a battery tender or trickle charger? I don't necessarily use my bobcat everyday to stay charged up... sometimes a couple weeks between use...

                Battery float charger/maintainers are a great idea....!!

                  if you are jumping battery to battery, wouldnt that really be the same as putting a battery in the machine?

                    That's what I would think. But if the battery is bad instead of just down that could be a problem. The fellow that works on welders over here says its got to be a good strong battery to weld right.
