Hello

I have an 1997 discovery RV .

Freightliner Custom Chassis Corporation (FCCC)

engine type : L6, 5.9L (359 CID) ISB 5.9-275RV

Allison Transmission : Allison 6 Speed Electronic Transmission

All worked fine until end of last summer when I ran out of fuel (my fault). RV was towed to my place where it sat there until today. I figured out how to start it again priming the fuel in . it ran for several minutes but as I tried to give it a test run the "do no shift light " was still on . the code recovered is OL 70 which is supposedly "sump pump fluid temperature too low" . I turn off the engine and since it is impossible to get a crank at the starter. No voltage makes it to the starter at all with the ignition on. the rear camera/tv and radio do not have any power as well. all fuses checks. the batteries are giving 13+ volts and are at 100% charge. I think these are all unrelated symptons but wanted to mention them just as well. Any suggestions welcomed. thanks

Symptons Lists recap :

no power to the starter on ignition

no rear camera or radio power

do not shift light stays on

Verifications made recap:

batteries 100% and 13+volts

all fuses in front of RV checked

I have the same engine, chassis and transmission setup on my 99 HR Endeavor. Last fall it wouldn't shut down when I took it in for state inspection. The problem was a faulty ignition relay. Try calling Freightliner or Cummins technical service. They may be able to guide you in the right direction. I have found these guys to be very helpful.

Bob,

thanks for the info . I did place a call and you are right : Friendly professional folks ready to help out.

I have possibly several causes to my starting problem . I will need to debug each one until hopefully I find the root cause.

1) Transmission says it is in neutral , but it is not. So the engine won't be allowed to crank. but this does not explain the power failure of the radio and rear camera.

2) Small Fuse VIM box in the rear of the RV passenger size needs to be checked for blown out fuses. it contains the remote starter relay.

3) fusable link power stud. these are wires in the front next to the firewall that could have blown out.

4) a dead starter. although it cranked fine it could have died right after starting the engine.

I will try out these 4 options until I find the problem(s) and post the solution when found for others to benefit from the learning. thanks much.

Forgive me for asking the dreaded "Is it plugged in?" question, but have you checked the chassis and coach battery disconnect switches? Sometimes these panels are located just inside the door, where it's easy to accidentally trip them. Good luck. - Dave

I was not aware of the existence of such switches. It is indeed a good thing to investigate. In the meantime I have resolved the main issue. It was a starter problem. although it cranked one last time, it was dying. I replaced it and the RV now starts without a problem. The transmission code reset themselves and except for rear view camera and radio not functioning, all seems to be operating OK. the radio and camera are most likely a blown fuse.

Your insight and suggestions have been unvaluable. I was able to resolve the issue in a much better manner thanks to the community support. I am grateful. thanks.

The battery disconnect switch on my 99 Discovery is on the panel next to the fridge along with the tank readouts.

Mine has not started twice over the years. Once was a fusible link that lives on the chassis back near the duallies. The other time a small wire to the starter was broken, $500 for about 10 cents worth of wire but I probably would have never found it! However, that issue didn't affect any of the other electrical systems. The fusible link took out all the dash power too but since you didn't mention that, I'm thinking its an unlikely cause.

My current issue is the steps. They won't retract. I have a new motor and controller on order but until I fix this problem, we are not going anywhere in the RV! Overall, we have had very few problems with our 99 D. We have around 100k on it and intend to keep it for a long time! Its likely the last new motorhome we will ever have and we have now had it for 13 years. After almost 10 years of fulltime travel it now gets used a couple of times a year.

If it's a Kwikee? the techs will be most helpful. You might also try checking the ground. That was a problem once with mine and the techs helped me remedy it.

Yes they are but I have +12 volts when the switch is one way and -12volts when it's in the other position. That tells me the switch is working but either the motor or the controller is not. I ordered a kit which includes both (a quick $239 with shipping). Hopefully,it will arrive tomorrow and I can have Libby crawl under there and replace them both!

John - I went through that several years ago. I just needed a motor, but it turned out Kwikee made a logic change that also required a new control board and magnetic door switch, because they changed it from normally open to normally closed, or vice versa . Quite expensive, but you end up with everything new but the steps. Good luck to Libby, and tell her to stay clear when she removes the cotter pin securing the steps to the linkage, or wear a helmet. - Dave

Yeah, I read that. I think it was pre 99 so mine may be ok but I'll let you know after I get it changed. I'll put Lib on the creeper and give her my bicycle helmet so she doesn't injure anything that would impact doing laundry or making dinner.
