Understanding the KSB
Working on a 5.9 removed from a Blue Bird bus. Installing in a old Dodge (Champion) motorhome. No wires on the motor. Have no idea what sensor to wire the KSB to? Also will it harm anything if it's not hooked up at all? Thanks in advance and have a great weekend.:humm:

You'll have to figure out which version KSB you have. One needs to be energized to advance the timing, the other cancels the timing when energized.
I believe the stock setup works with a temperature switch, but it can be placed on a toggle switch too. |
Would it matter to leave it disconnected? This particular KSB is mounted remotely. It uses line pressure to go to a port right beside the inlet port for the fuel line. Being it is in a motorhome cold weather starts SHOULD not be a issue. I truly do not understand what the KSB is to do? Thanks for the reply.:argh:

It is not a starting aid - merely a pollution control device to reduce unburnt fuel on cold startup. That being said, on active KSB's, they probably run energized most all the time in cold weather. The timing will help with a little better fuel economy in cold weather, but you would probably not notice it and it won't hurt anything either way.

Sure is a whole lot of crap over a little bit of smoke. Thank you for explaining more clearly how this works. On the next problem. Have a great weekend.

Good read here...
Non i/c KSB vs. I/C KSB - Dodge Diesel - Diesel Truck Resource Forums If its the early one that needs power to keep the timing 'normal' you can take power off the fuel solenoid. Its not a good idea to run the extra advance all the time. Double check, but IIRC, warm-up and higher rpm highway use are where the extra advance helps. |

Why not? I know guys who've jumped a tooth on the timing gear to get more timing than is possible with the stock setup.
