G6200 glow plug indicator not glowing - hard to start

[jgvt]

G6200 - 975 hours. Probably 1990 circa. I've owned this tractor for 11 years. It has always run great. Primarily work on it myself, fluids, belts replacements, etc.

This season the glow plug indicator wire is not lighting up like it has in the past. Today it took numerous attempts to start - did not see the wire get red. The tractor may have finally started because it was so hot out - 90 degrees.

Totally newbie questions here
1. Would a weak battery be a possible cause? Battery has never been replaced.
2. How would I diagnose if the glow plugs were worn out an needed replacement.
3. Anythings else people think I should be looking at.

First post - thanks for the help

Use volt meter. Should be above 12 volts full charged. On 24 volt system, still make sure above 24 volts. I like the battery tender plus since you cannot over charge the battery since it has a microprocessor built in to let you know when done. About $70 for the 12 volt and $126 for a 24 volt version. I had watched a few YouTube batteries about kubotas and it appears that for power, the owner had 2 12 volt batteries he replaced. Not sure of the glow wire. Hopefully someone with a better knowledge can answer it.

Start with a new battery, after 11 years it needs a new one, and yes this would cause it to not heat right. I'm sure your glow plugs are okay.

Great - thanks. I'll pick up a new battery

if the tractor is spinning over fine you should get a volt meter and
see what the voltage at the glow plug wire is. if it is spinning
motor good battery would light that.
