MEP 803 Voltage Regulator

[justicelee26]

Just got a new voltage regulator that seems defective. My old one still works but will spike the voltage after operating fine for a while. I asked this question before and didn’t get any responses so I figure I’ll give it one last go. Is there any alternative to the stock voltage regulator? My brand new one isn’t regulating when I release the master switch from start so I’m looking for a more reliable option. Thanks.

I didn't get into this thread, as I like to fix things, and doing a mod, just isn't my thing. BUT, I do seem to remember hearing a long time ago, of someone in the forum installing a non standard Volt Reg. Cant remember who, what or why, as its not my interest. But I think I remember reading an old, old thread about it.

So, are you sure its the same volt reg? The 400 hertz volt reg looks the same. Are the part numbers the same as your old one?

If you bought it, and it doesn't work, cant you send it back?

You called it new, is it? Or a take out?

Thanks, I’ll try to find that old thread. The new voltage regulator is the exact right part and I probably will send it back. It is new and looks perfect but right after I installed it I was only getting 30 volts out of the terminal lugs so it just didn’t seem to do its job. If I was better with circuit boards I would try to fix both but I’m just looking for a better solution at this point.

Guy,
Maybe you're thinking of this thread about using the SX460.

Kurt,

Roger that. I just didnt pay it much mind, only "kinda" followed it. Thanks for finding it.

Did they say what parts they had to replace? How much was the repair cost?

I'm not an electrical guy but I think it was some diodes and something with a heat sink. I don't remember how much it cost but it was worth me doing it vs. the cost of a replacement
