Message: <blockquote data-quote="we7hills" data-source="post: 101301" data-attributes="member: 15578"><p>part 2 continued: bucket will function again, briefly OR as long as the RPMs are < 25%. I also noticed that the hydraulic charge light would intermittently "flash" on for a second once in a while especially when I was operating the bucket/boom on "high," so next I checked hydraulic oil level, which was about 2.5 gallons low due to a very small chain-case cover leak. I added fluid to correct level, but still have the same SOL LED issue - won't stay lit above 25% engine RPMs! Per further research, and suggestions of possible clogged filters, I have ordered all new filters, and will change them out as soon as they arrive. However, the hydraulic fluid is crystal clear (because I add a gallon or two a year due to that small leak, described above) so I am not leaning in that direction, but rather "poking and hoping" right now,... trying to resolve this "gremlin" as quickly and correctly as possible for the least expense. OK, guys,... What else can I look for to troubleshoot this SOL LED Gremlin? It seems strange that for 7 years it ran fine, then all the sudden, BANG! SOL/LED control box issue? This makes me think the control logic box is the issue, but if so why are the RPMs affecting its operation? The RPMs affecting it is making me think the hydraulic pressure / flow could be the issue,... Is there another way to test the control box function? As per the detailed instructions in previous posts here, I have verified all the other control box LED lights function correctly for order and sequence,... I read one post that a guy "jumpered" the 12v out of the seat safety switch directly to the SOL Valves as his SOL LED output was only 2v, but I am assuming his SOL LED light was "ON" but control was malfunctioning, not outputting the correct 12 volts? I can (and WILL) jumper 12v to the SOL Valves if the control module is bad, ($700 for re-manufactured unit!!!) but I would only to that as a last resort. I work in the Nuclear industry and BELIEVE in safety (unless it costs too much!) so I would rather have the safety features function correctly if possible,... and I don't want to damage my pumps if it is a hydraulic issue. What should the control output voltage to the boom / bucket SOL Valves be? Or doesn't that matter if the SOL LED is OFF? Why would the SOL LED on the module function at</p></blockquote><p></p>
