 Topic: 8010 power director
Posted: 03 Aug 2025 at 2:53pm |
|
I had trouble with the 8010 this spring planting no high side on the power director finished planting with backup tractor and just getting back to fixing it. When I shift up it blows the 15a hyd. alt fuse. I have checked the wiring and kick down switch on the clutch and found nothing wrong. Checked solenoid and got 1.3 ohms which I would guess is very low, with the solenoid disconnected I can upshift without blowing the fuse. The solenoid is NLA. I haven’t called about a salvage and was wondering what normal ohm reading should be to make sure I don’t by one like I have. Any tips or suggestions greatly appreciated. Thank you

Google says a typical solenoid has a resistance of 20-40 ohms.
I'd guess yours is shorting out, as you pretty much proved by not blowing the fuse when you disconnected the wiring from the solenoid and didn't blow the fuse.

Found a new solenoid at Heitman tractor. They said they had 3-4 left and when they’re gone that’s it.

There's likely a brand name and Mfg parts number on the solenoid. Probably can't read it on a 40+ year old that's been in use, but those news ones should have readable numbers.

If memory serves correct the early power director spool/coil assy was replaced with a coil and spool that were 2 piece. The latter coil is available. part # 79028135

You are correct but they are not interchangeable

The one for early serial numbers has 2 prongs that plug in 1 black and 1 white and goes in from the bottom up. The newer one looks to go in from the top and I believe has 3 wires.
When the new one gets here and I get it changed I will check for part numbers on both of them and post.
Someone may be able to cross numbers to find what CNH part is the same.
I didn’t put 2&2 together till now but the tractor would drain the battery from time to time if it wasn’t used for a while and I couldn’t find the cause so just started disconnecting battery cable if it wasn’t going to be used for a while. I’m betting the solenoid was the cause.

Dad & I bought an 8070 about 10 yrs ago with a bad power director solenoid. it was the earlier solenoid & the coil was NLA. We found Santa Fe Coil online & had a replcement coil made. Not cheap but out tractor went from a 10 speed back to a 20 speed. We have not had any problems for the last 10 years with it

Well some progress. The new coil is on and the plunger on the solenoid goes up when I shift to high but drifts down and there is no response from tractor when I shift. The old coil had a melted spot on it so it was at least part of the problem. Not sure what to try or look at next. Any suggestions on what to try next? It doesn’t blow fuses now. I got some numbers off of both coils and will post when I get back to the shed. Thanks for any ideas on what to look at next

Check the voltage on the power wire, sounds like something could be faulty. Either the wire itself or the switch.
