How long should the glow plugs have voltage for when starting

Dan,

Approximately 30 seconds -- see the last paragraph in the description below from the TM1591...

I put my meter on my 332 and also 430 both would have voltage for 10 seconds. The 430 starts great but the 332 starts hard.

Daniel-
You may have a bad glow plug. It only takes 1 bad one for the Yanmars to start hard. Have you tested the glow plugs themselves to make sure they are working correctly?

Forget to say I put new glow plugs in about a month ago.

Did you do OEM plugs or others in the 332 and what does the 430 have? The OEM plugs have a ramp up where they get hot faster then other plugs that fit from what I have read. Not worth the extra cost-I just cycle the plugs a couple more times depending on the temp. Also-even new parts can fail-that is why there is warranties-to fix the defective parts.

Could the fusible link be weak I have 13 volts at the battery but 10 volts at the glow plug

 

[knottyrope]

you could have a corroded ground, or at the relay pitted contacts. check all wires on that circuit and you should be able to get 12v at the glow plugs.

you are losing about 20% of the heating power

There have been a lot of people that installed a relay similar to the starting kit for the 318/420 to get full voltage to the plugs. Basically it uses the voltage you do have to switch the relay kit on to then get almost direct power to the plugs.

Checked all the glow plugs are working good when I turn the key on I have power to the glow plugs for 18 seconds and all the way down to 10 seconds. Should they glow plugs have voltage for a full 30 seconds

 

[knottyrope]

yes they should have full battery voltage for about 30 seconds
