Original issue: Boom & Bucket Hydraulics "locked out" by SOL LED on Control Module. After troubleshooting all connections and harness to module, the FINAL resolution was that the internal rectifier diodes in the alternator had FAILED causing the alternator to produce a continuous 17.95 volts...

This is the label inside the existing regulator: TRANSPO#: IY786 And these are the cross-reference parts: AMSCO#: MD-24 WAI#: 35-8601 TRANSPO#: IY786 OEM#: 12449, 42786 LESTER#: 12175 FITS: MANDO ALTERNATORS USED ON BOBCAT, KUBOTA DETAILS: 12 VOLT, A-CIRCUIT NOTES: BLACK, BLUE, GREEN, RED...

May have identified cause,... Tested Alternator: cranking 17.99v at output post & feeding 17.45 to battery! Alternator has external but integral voltage regulator and condenser attached to back. Volt Reg has adjustment pot, but it had no effect on output. Suspect malfunction of Voltage...

I'll keep trying,...

I have many more details and observations on this issue, but haven't learned to post correctly yet,...

New post, Old issue, Troubleshooting 10+ days. 1990 NH L555 D. Boom/bucket function & module SOL LED light cuts out. Shutdown & restart, or RPMs harness & diode/resistor. 12.8v to seat, but 12.2v to module; a .6v, drop but not as specified 1.2 to 1.6v. Replaced harness. Double-checked seat...

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...

SORRY! The system won't allow me to post my whole narrative ( I guess there is a word limit?) AND it won't let me add the remaining text in a reply, AND it won't let me delete the incomplete text, OR the incorrectly entered text! NEED ADMIN HELP, PLEASE!

Additional Info: OK, my question on battery / system voltage was an inquiry after reading the following comment from ruko_ruko: "...I became aware of a probable low voltage situation when I switched to "service mode" on the module and turned the key to start, the start relay would just click and...

Could it be low/bad battery? The battery is only a year old, and I keep it on a battery tender all the time,...

HELP! PLEASE! SAME ISSUE! I realize this is an older thread, but I have a 1990 L555 Deluxe with almost the same issue,... I can start her up, and everything seems to work fine, but I only get few operations of either the boom or bucket before the SOL LED light on the control module goes out. If...
