L3302 how many glow plugs.

[whatsupdoc]

I happened to take a look at the L3302/L3902 shop manual wiring diagram and noticed that it shows a single glow plug. Im not near my machine so cant take a look so does anyone know. Just curious.

trick question?

3cyl = 3 plugs shown by 3 lines??

but maybe I be stupid on this one.

I believe that is the symbol for a chassis ground, as compared to an earth ground symbol which is normally an inverted triangle with three lines.

if you notice the starter in the wiring diagram uses the same ground symbol.

3 glow plugs .
A single wire comes off the relay to one glow plug and then a strap connects the 3 together .

They went to a common symbol for the glow plugs as some models of Kubota's have grid heaters and some have glow plugs.
I doesn't matter if there is one grid heater or 1, 2, 3, 4, 5, 6, glow plugs they are all wired up the same way, common hot, common ground.
They have since just after the L210's 50 years ago.

The L3302 and the L3902 still have 3 glow plugs.
