Proud new owner of a 1967 580CK gas. Not much to look at but it has strong hydraulics, easy start (when it wants to) and runs out nicely (when it wants to). The "when it wants to"'s are where I could use some troubleshooting advice.
The nice fellow I bought the CK from told me that he thought generator was going bad but he just kept a charge on the battery and had no issues with operating the machine. First time out to play at home the CK started right up and ran strong for about 4 hours. Then it started to sputter, lose power, and after about 5 minutes of this died. I checked the battery - it was drained. So I charged the battery and it started right up. Worked again for a few hours and same thing - sputter, lose power, die. So then I jumped the CK with my truck. When I pulled the negative cable off the truck battery the CK died so it confrimed, at least to me, the generator was bad. Pulled the generator and had it checked - was indeed bad so I had it rebuilt. Put the generator back on and tried to start the CK. No luck. So I jumped it again with the truck since I had not charged the battery and it started up. When I pulled the negative off the truck again the CK died. Decided to check the voltage regulator. It was pretty roached out so I replaced it. For good measure since the battery was 10 years old I replaced it too.
After the rebuilt generator, new voltage regulator, and new battery the CK started right up, no GEN light, and ran great. I did not operate it for any extended period of time but started it daily for about a week with no problems. This weekend I was using the CK and after about an hour of work same thing - sputter, lose power, died.
Can any of you seasoned gents offer advice as to where to look next?
