You may get all your trailer lights if you run a jumper from the brown wire to the black wire. The pins in a standard 6 pin plug are 1 oclock and 11 oclock are tail and clearance lights. Try checking that out.On the ranger it sounds like you might have a bad fuse in the dash light cicut, Just check it.

Use this web site hope it will ease your pain :-)

To the management and staff at Watts Mack Thanks for helping us do the jobs we do.

Happy Holidays to All, Be Safe, enjoy the time with loved one's!!!

I work for a shop and we have various model Macks the one that we are having problems wiyh is a RB690S. Every once in awhile it will not start, it cranks fine but will not fire up and then if you leave the truck sit for a couple of hours it will start right up. Has been to Mack dealer for this problem but they could not find anything wrong. Was wondering were i could find any information on the shutdown system on this truck. It is an electrical system not a cable shutoff. Where is the solenoid or sender actually located on the pump and is it difficult to change ? We have none of the current model engine ,vmac instructional booklets and do you know anyplace to get these booklets without spending an arm and leg ? Or is there a website that has all the information like a motor manual ? Thanks for any information provided.

check the tach sensor on the left side of the bellhousing,I have had the plug spread on some rd690s,rd690p 2001 and found that to fix it.

As a fleet mechanic I will tell you unless you are running 1000 lights you only need about 13,13.5 volts for running and normal ops. Most all vehicle accs. claim max volts to be 14 or so. Remember if you look at an analog gauge it never reads as accurite as a digital. Just to be sure you don't have a battery issue take all the jumpers off and load test each one separatley.If you can check the specific gravity(hydrometer) that will show a bad bat too!

does anyone have a picture of kysor water alarm relay so i can see whats written on it in relation to terminals???mack want $350 for new one and want to make shore its the problem before i buy one,thanks adrian
