jeepwm69 7,719 Posted February 12, 2023 Brother in law just dropped off a 98 450 ES, says no spark. Very clean machine. Diffs are rear brake panel are still shiny aluminum, meter and gas gauge are still clean and clear. Battery is dead, so will have to put one on to start troubleshooting. 1 Share this post Link to post Share on other sites
Goober 1,555 Posted February 12, 2023 That’s a full time 4wd right? No power steering. No fuel gauge. Downright simple except for ES. Wonder if it gets an oil light right away. Share this post Link to post Share on other sites
jeepwm69 7,719 Posted February 12, 2023 I will have to look for that again. I don’t believe I did see the oil light come on. No error codes. Had a foot shifter installed. N showing on display and green neutral light is on. What is this thing? Only one wire had power. In the battery box next to fuse box. 1 Share this post Link to post Share on other sites

I’ll look it up in the schematics Starter relay. Starter works fine. Just no spark. https://www.partzilla.com/product/honda/38501-GN2-014?ref=901f85ccb24e3560ed23b4bec6380a53678df829 I have the FSM on my computer at work. Will dig into it tomorrow.

shadetree 5,969 Posted February 13, 2023 if i remeber correctly ?, if the fan control does not work on this model ?, the oil light will not come on shortly, then it won't fire spark plug. Share this post Link to post Share on other sites
shadetree 5,969 Posted February 13, 2023 also, check out the reg/rec, a bad reg/rec will stop it from firing, case in point, watch this video --> No spark problem Fixed!!! 1998 honda foreman 450 better picture - YouTube , he also covers the c.d.i. , but in detail, it was a bad reg/rec. 1 1 Share this post Link to post Share on other sites

This one happened to have a Chinese/aftermarket voltage regulator on it. After checking cross reference I took the one off my kids 05 350 rancher and put it on this 450 and it fired right up. Placed an order for a replacement regulator from Powersports nation for a hair over 15 bucks. Told the owner to bring me a 30 pack of Miller light and an 18 pack of Mich ultra for the wife. 3 Share this post Link to post Share on other sites
