NH TC29 DA starting problem again

[ranger13256]

My 2005 NH TC 29 DA starting problem is acting up again (still). I replaced the battery, battery to starter cables, new NAPA starting switch. After all that , it started fine for a few days then back to its click, click, click then start routine. The glow plug seems to be operating normally. Sometimes when warm it starts normally, sometimes not. Could it be the starter?

Have you installed the dedicated starting circuit? My TC33D was acting like what you have described until did this modification, that was probably 20+ years ago.
