SN: K061644 with a EV100 panel. An error code 3373 comes up which is not in the Yale manual and is one we have never seen before. The truck jerks hard in reverse and forward as if the truck goes straight to high speed and then shuts down completely. Traction motor light and service indicator light comes on as or after the problem occurs. There is also evidence of arcing in the main panel and at various contactors. Any advise out there.

Hi, there
i`m interesting for YALE shop manuals..
Could anyone share any info. about yale with me
thanks
You know what too...
Anytime I get error codes on EV100's I pull the 4 (sometimes only 3, yours will have 4) connectors that plug into the card and replug them in. That cleans those connections. Dirty pins there are a known problem with EV100's and SX cards and can cause all sorts of codes. When that works I unplug again them and clean them. Clean them with a good NON-conductive electrical cleaner and use a good dielectric paste in the pin holes (GE says to use NYOGEL 760G from Nye lubricants, which can be bought online). DO NOT smother paste onto the pins in the card. Just a bit in each hole in the wire harness plug.
I still have to take a look at the book but...
If 3373 really is the error code, Maybe you have a bad display panel? Do you have a handset? Assuming the 33 is a malfunction. Maybe the code is a -73?
-73 would be the GE code for a defective RB contactor. It would give you the PMT (pulse, monitor, trip) condition you are experiencing (the jumping). If a EV100LX (or newer) truck does that jump, it absolutely should display an error code.
Does the truck have regen? If so check that the regen contactor pulls in when the truck turns on (it should drop out when truck goes into regen). It has to be closed for the machine to run in normal forward or reverse.
Check that it isn't dropping volts across it when it's pulled in and that the tips are good. Check the wire at PA6. It connects to the A2 connection to the RB contactor. Make sure all those cables and wire are tight and have a good connections.
A few different codes will cause that jump. Defective RB, F and R contacts will throw a code (code 24 for directional contacts). Lose cables can look the same to the EV100 as bad contacts. Where are the sparks coming from?
lotto numbers hahaha good one john :o)
i might have mentioned (if) the unit had premium hydraulic controls it would give a 3 digit code but i failed to mention that it also displays its hour meter reading after the drive meter, this may have been what you are seeing.
Premium hydraulics would have a 2nd control system mounted on the right hand side of the rear compartment just like the drive side, in effect 2 ev100 control systems side by side... does this unit have this?
If not and you only have the one control system on the left side of the compartment on the main panel then its just a standard contactor controlled hydraulic system.
hey chickenbone, all is well that ends well but one of two things come to mind on tehphanton 3373 code 1. the tech was messing with you and gave you his luck lotto numbers (that haven't paid off in the last 14 years). You do have lotto north of the border? I know you have casinos and great beer, I left a bunch of $$$ in Windsor or enough for them to buy 2 gallons of paint to keep the casinos looking good.
2. The Yale ZF version I believe has solid state hydraulic motor control - that 3373 could have been mistaken for the # hours on the pump motor - just a SWAG from south of the border (actually north of the border from Detroit area). The ratio of 6000 drive motors to 3373 pump motors seems to be in the ball park or hockey rink. What say you?
I don't doubt that the 3373 could be an hr meter reading. What is confusing is that the current hr meter reading on the truck is in the 6000 hr range!! It turns out that the tech did not have our LX hand held analyser with him when he first went out to analyse the problem. When he went back he was able to plug in and the analyser gave him codes he did not have earlier. He isolated the #II rec by taking a new SRC , ("a known good part") and plugging it into the panel in the various locations until the symptom went away. Thanks for your comments on the the problem being a phantom. We will keep it in mind since as you say since the symptom (failed rec) could be a symptom of something deeper.
that is rather odd, i still believe that 3373 code was actually an hour meter reading.
as far as the scr2? i find it odd it didnt throw up any codes like 44,45,47,49 or 50 as all those codes are related to the 2rec.
and of course if it was hydraulic related it would be the same codes but in 3 digit such as 144,145,147 etc.
But in all actuality all these codes are basically general codes related to some type of failure in that circuit and there can be other reasons these codes could be triggered that are not even related exactly to how the manual describes the symptom and related components. They are just guides to help find the actual problem.
All in all it is good that you found the issue and got it repaired
good job!
Lets just hope you didnt repair a ghost problem and it doesnt return at some later time, its been my experience to go ahead and check all the other scr's while in there because sometimes this can come back and bite you ;o)
Everyone. Thanks for your assistance. It turns out that is was the SCRII. We will probably never know what the 3373 code was. Chicken bone
yep that error code you posted looks more like an hourmeter,
with this truck you will get either a 2 digit code for drive system codes or a 3 digit code for hydraulic if this truck has the premium hydraulic panel in it.
sounds to me like a PMT trip but the jumping and then tripping out sounds like a shorted component
if the truck is jumping as soon as you engage the accelerator it could be stuck 1A contactor, or a bad 1REC, 4REC
i'd check those first before digging deeper
It looks like that could be one of the roads we will go down
Got your e mail. Many thanks
Hi Mate
Unlikely to be the error code, but the problem sounds like one of the thyristors have failed. Best thing to do is check the standard components, and make sure the connection on the snubbers and the connection underneath it which connects the capacitor to the coil has not gone loose.
Hello.
See your email.
Best regards, Laci
