attwood furnace

I recently purchased this used 2004 r vision lite and furnace valve was leaking, ordered new regulator and installed today. It is an Atwood 8531-IV-DCLP
Now it will not lite. sounds like the motor is running slow and do not hear a spark. Not sure what to check now. I did adjust the spark rods to 1/8" they were about a 1/4 " before. I can pull the regulator and flame unit back out and re check everything. Is the motor supposed to run slow or fast. seems like it did run faster before. No Idea where I screwed up but I am looking for help if anyone is familiar with this furnace.
  • with battery charger hooked up furnace works just like it is supposed to. Really feel like a dummy now but live and learn
  • Just happened to think I am on battery only since I cut the plug of the camper wire with my lawn mower. Yea I know. I get a new plug wed so I will try after its plugged in to power.
  • If the unit d0es not come up to correct speed the sail switch will not close. If the switch does not close the gas valve does not open
