Rewiring my '02 24V Dodge Cummins for the ambulance alternator, 600A of transient surge current, 24V FLU jumpstart capability and such, brings up the "fusible link" issue. It's more of an older American car/truck thing -- fusible link is a short run of wire, about 1/2 the gauge of the primary wire, meant to burn through without catching fire. Instead of a fuse. Do I add fusible link to my thicker-gauge rewiring job w/ milspec battery-terminal clamps, or go with an ANL fuse...?
Our German-American FLUs are a mixed bag of SAE/metric. My question for y'all re-harnessing ratfood wiring that's all black and such... anyone come across fusible link anywhere?
That flash I saw engaging the lockout the other day, doesn't correspond to any blown (euro-ceramic) fuse, or spark-mark on any of the handful of relays (none of which stop the pump from cavitating, above the "min" mark on the reservoir, bought an old-school metal gooseneck funnel yesterday to even get fluid into that reservoir after removing the barely-accessible banjo fitting and wishing I'd at least brung a turkey baster), let's not argue semantics and just agree this system isn't very well thought-out.
Next time I'm up at the jobsite, I'll be looking a little down-wire for some blown fusible link, to account for that flash I saw. As it is, I think putting some fluid in, will set the lockout to rights? If it can complete its cycle without cavitating (in operation, fluid sucks down to way below the "min" mark from just above it, on my HMMH), it should shut off, and revert to cycling on once every 10-15 minutes like before?
The weird noises I hear, now that I've got the metal cover off etc., correspond to the electric/hydraulic pump intermittently sucking itself dry, until enough fluid drains back through that banjo fitting I'm gonna remove to top it up, for fluid to pump again. Then I'll either fix or replace the existing reservoir, and be happier for having figured out just how the **** this retrofitted-as-afterthought-to-begin-with, barely-documented system is *supposed* to work. So I can figure out how to re-do it properly.
Retrofitted afterthought = not part of the original design, maybe before 1 HMMH was built, maybe after all 164 had been built, who knows? "Git 'er done" for 164 units, seems to have been the concept, the double-fuse-holder with only 1 fuse/ring terminals on it -- if I'd done that post-auction it wouldn't be a **** old-school euro-ceramic fuse. My HMMH is not intended as a garage-queen OEM NOS showroom-stock piece of useless equipment, I need it to work, and it's looking like time to throw out at least the wiring on the lockout, so why not most of the rest?
If only there were more feedback than me, and the other guy who disagrees with me, on these! Or we knew if the HMEs have lockouts, etc. There's going to be a "right way" to do this, and IMNSHO it oughta be plumbed into one or the other hydraulic systems on the FLU, instead of being a third which requires an hour of work to check / top-up the fluid level? Crazy. I've just gone through this with my newly-acquired from Southern CA '95 CTD dually and service body, completely impractical wiring for blingy purposes unrelated to getting work done. Spaghetti wiring.
A little more feedback, both the HMMH forklift and HME blade questions get answered in a way which tells me how to make it work properly, as opposed to just getting it done. How I roll. I don't care how the lockout on my HMMH "should" work or "should" be wired. Wish I had an HME so I could figure out one system which works for both (if the HME even has it), which would also work for SEEs if, like, you have pallet forks on your loader bucket or something, and want a simple lockout upgrade. I may be wrong, but I'm done arguing about something nobody really knows about for certain. If, as an owner's group, we can work something out between us, I'm sure we can work together to build it! Let's just agree to get along.
Nutshell -- I am *not* a fan of the front-suspension lockout on my HMMH, regardless of what anyone thinks about needing it or not, for one task or another, or whatevs. Plenty of room for improvement. Filling a hydraulic reservoir should be obvious, not require crawling under the truck, tracing all kinds of lines to see if it's even connected to the other two reservoirs, etc. I'm not beholden to any of it.
