I think 1 volt/bar when expressed in db you need to add 200 db to get reading in volts per micro pascal.
Fairly straightforward to change the tdi glow plugs. They are located on the near side of the engine and the first thing to do is give them a good airblast to remove any debris and stop it falling into the glow plug hole after you've remove the plugs. Next loosen the top nut on each glow plug and slide away the connecting bar. Remove the plugs the same as you would spark plugs (ie with an appropriate size socket) and replace them with new plugs. Make sure top nuts have enough space to slide the connecting bar back into place - tighten holding nuts. Job done.
Yes.
120 volts and 240 volts. Typically 240 volts is supplied to the house electrical service entrance. It is split into it's 120 volt components via two buss bars. Hooking a circuit up to just one bar yields 120 volts. Hooking into both gives 240 volts.
The terminal strip's rating is 15 amps at 600 volts. It does not matter what the voltage is up to 600 volts, the maximum amperage allowed on the strip is 15 amps. It could be 15 amps at 12 volts or 15 amps at 600 volts or any voltage in between.
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
no because it may short and cause a fire
Bad ground in your home. 1 bar is 60volts 2 bars is 120to volts.
If it's the metal bar near the spark plug that you push towards the plug to kill it, all it does is ground out the plug, making it not spark. That bar is connected to the frame of the mower ie grounded which in turn grounds out the plug and wire
Undo the bolts on the top of the glow plugs that's securing the rail in place. The with that removed take the glow plugs out deep docket and a longish bar is a good idea as then you get out the way of all the pipes and wires ect
at the back of the engine, under the bar near the top of engine
The power-bar must be plugged into the correct voltage it was designed for.
