1990 fleetwood bounder 34s electrical newbie help

So I’ve been having problems with my engine which is a Chevy 454 7.4 HEI and it is giving electrical shock on spark plug number two. Also my fuse box has a charging light that will go on and off randomly to charge my house batteries which I’m guessing could be a grounding problem but it only happens when I lift up the panel where the wiring is. I don’t know if the guy before me did a bunch of other aftermarket stuff there is a gear vendor overdrive/under drive system on this along with a trailer braking system and the inverter that came with the RV is a quasi-wave or something like that and it does not work even being hooked up directly to the wiring of the rv. I’ve been burning through plugs like crazy and I am driving from New Jersey to California. I didn’t have much time to do a lot of research but the motor seems strong and I’m already 3/4 of the way there LOL thanks for your help in advance any tips would be awesome also my steering is pulling to the right a lot and is very sloppy I’m guessing I need an alignment and possibly new front end controls like ball joints tie rod ends And such. Any information would help the RV didn’t come with a booklet but not for everything right now I have to Fit a Duramax generator into it as my own and needs some work done. Thanks

  • Do a full tune up, plugs, cap, rotor and wires.
    Repair the existing genset
    Front end work needs to be done by a shop that knows GM P-30 chassis. Ball joints are not as listed on most parts outlets. They are shorter and fatter then those listed. Bell cranks are a problem on P-30s. Get ones from Henderson Lineup, Grants Pass, OR.
    Need to trace out wiring. You maybe able to get wiring diagrams from Fleetwood. Need serial number and VIN.
  • You may well be close to the point of no return...dump this RV and buy another that hasn’t been modified.
  • On the spark plug issue.

    Park somewhere where there is very little light at night. Open the hood and start the engine. KEEP YOU HANDS OUT FROM UNDER THE HOOD ! Wait until your eye adjust to the light, and then observe around the spark plug wire and cap. Use a spritz bottle and mist around all of the plug wires and the cap. I'll bet you will get a very nice "light show".

    You will probably need a new cap, rotor, coil and wires.
  • Check to make sure that the spark plugs that you are using are the right ones. You may want to switch to a cooler spark plug.
