Mike, post a picture here. I'd like to see what it looks like.

Kinda tight but here ya go Brad




I was able to find some info yesterday on troubleshooting slow engagement issues related to the settings.

Man, they got right back to me, impressed. They sent me a pdf copy of the instuctions. Not sure how to copy and paste it here. Ill keep trying.

Physically your's looks to be the same as the one's that I've used.

You should be able to post the instructions to this thread even if it's a pdf file.

Heck....if it was easy, everyone would do it. Working on these old motor homes isn't right....if you were an inchworm working underneath would be easy. Tell me you haven't bent your body into various shapes just to get access to interior items and then forgot a tool. Ahh.....

[bkahler]

There are definitely times I wished I was double jointed

I cant seem to get the whole pdf to copy and paste on my ipad but here are the 3 pages that address my slow engagement when setting the cruise control. Looks to me I need to check my current settings on "gain" and "engine set-up".





Ill have a look tomorrow how they are currently set. There is a note on one of those pages that says that these settings assume 1/8" slack in the throttle cable. My bead chain has a great deal more slack than that.

Mike, the chain slack can have a big impact on how fast it respond when you set the speed. I'd take care of the slack first and then change dip switch settings if need be. The longer the chain slack the longer it takes the servo to reel in the cable to where it actually moves the throttle shaft.

On my old 310 the settings for gain are:

1 = off
2 - on

For engine setup:

7 = off
8 = off
9 = on

Good luck!

Thats my thinking too Brad. I looked at the chain slack today and it seems very loose. I was able to tighten it by one bead without cutting it. I dont want to cut the chain until Im pretty confident thats the solution. I think Ill wait till after the get together before I do that. In the mean time I will double check the settings. It looks to me that the gain and the engine set can also affect the lag time or slow surge. Ill take a look at those in the morning.

[bkahler]

Before cutting the chain I would try dip switch changes. It's really easy to flip the dip switch back the way it was if it didn't help. Adding a bead back on the chain not so easy

[mayco]

Looks like my settings can be changed to help resolve the lag time for engagement. Currently my "gain" is set to mid and my "engine set-up timer" is set to low. I think Ill start by resetting the engine set-up timer to high. I really appreciate your help here Brad. I really had no idea about these switch settings, I assumed it was in the linkage. (Which still may need shortened)

It reads to me that I need to turn #12, control switch, off, ignition to off, reset switches then control switch back on. Ill try to find some more info before I start though. I dont want to risk driving to Penn Wood without cruise, two hip replacements makes for sore driving without cruise.

Mike, it sounds like you're talking about dip switch 12 and turning it off.

I might have misinterpreted what you're describing but just in case, the steps required to make changes to the dips switches is to slide the on/off switch on the control stalk to off, turn the ignition off and then make the changes you want to the dip switches and then go for another test drive.

I got this from the installation manual:

NOTE 3: If any of the twelve (12) switches need to
be changed after installation of the GlobalCruise,
the control switch and the vehicle ignition must be
in the OFF position; this is to allow the
GlobalCruise to RESET.

Ahhhhhhh, ok. Well thats essentially what I did, and diconnected the negative battery cable. Their instructions were a little vague, they call #12 a control switch. But, I did turn off the cruise control also. So, I think I should be ok. Have to road test still.

[bkahler]

#12 is where you tell the cruise control module what type of control switch that you have installed. There are two types, open and closed. Not sure what you have but you shouldn't have to touch #12 since your cruise control is working properly as far as operatino goes.

You also don't need to disconnect the battery. The main thing is they don't want you driving and making a dip switch change at the same time

[mayco]

Thanks Brad. Well hopefully I didnt screw it up!!!!

[mayco]

This is where I saw to disconnect the battery before making changes in switch settings. Oh well.

Well that's interesting! I had not noticed that little blurb before.

I can't say that I've ever had problems with the dip switch setting changes taking effect, but when I was working on both vehicles (Triumph and 310) I was doing a lot of different things at the same time and frequently disconnected the batteries for a variety of reasons.

Sounds to me like you should follow the note and disconnect the battery. When I finish the Rostra install in my Argosy I'll have to test disconnecting the battery and not disconnecting the battery to see if it really makes a difference.

Thanks for pointing that out!

Just finished our first leg to Penn. the switch changes made all the difference. Thanks for the help Brad. It engages immediately now!!!! What a great improvement.

Good deal! It's always nice when things work the way they are supposed too
