Naomi Game Issue (has just got worse)

[wonderbanana]

Cageman you are a star for doing that - many, many thanks!

I'll try and pick up a meter this week

[wonderbanana]

Don't suppose someone can recommend a Multimeter from Maplin or eBay?

There seems to be quite a few variants.

[cools]

I have one of these:

I got it specifically because it can measure monitor yokes as well as all the other stuff.

Looks good I'll confuse myself senseless with that

Just be sure that if you are using an adjustable power supply on a Naomi that you do NOT put it at 5.2 or higher. It'll damage carts.

****.

Not had a chance to check the PSU yet but I'm worried.

Zero Gunner 2 just came up with Error 1 in use. It had been on for 2-3 hours and bam it just froze

No amount of plugging it in and out seems to get it working

I'll bag a meter tomorrow.

If the cart is borked, I assume it can't be recovered?

I'm going to be so bloody gutted it that is the case

Silly boy shouldn't of run anything till you'd checked those voltages really Other games still work or haven't you tried them?Hopefully its the mobo.

Tbh matey I'm not gonna plug another game in till I check the voltage going to the Naomi.

What other voltages (and how?) should I check on my PSU? Seems wise now to check them all. Other main board I run atm is a Sega STV.

I've never even removed the cage that surrounds my PSU. Other AWSD users here, any advice?

[wonderbanana]

Hopefully its the mobo.

Yeah that would be cheaper. It does still 'boot' to the Naomi screen though.

Could well be the carts been on its way out for a while, the voltages might not be an issue it could just be ****.Had you had the other carts running for any length of time?

[thechop]

Are you powering it straight off the JVS connectors or through a Capcom I/O off the Jamma edge?

Yeah they have been run for a good few hours but this has seen the most use overall.

This cart was a pain to get going from the off (hence this thread).

Will check voltages tommorow.

I'm actually hoping if it is borked that it is my psu set too high as I'll be royally **** if it was already on the way out.

I'd say its more likely the cart was dodgy in the first place tbh as none of the other carts have shown similar symptoms only that one cart.

I don't know how quickly they burn out tbh. I guess tomorrow could be interesting.

Top tip always use the least expensive cart as a test subject(i know you don't wanna hear that ), but do go to Maplins you can get a multimeter for £6, more than adequate for just testing your voltages

Will be my first port of call in the morning Was just starting to get better at the game too

How do I check the other cab voltages? In fact, what power do I have coming from the PSU? (AWSD)

[thechop]

Are you powering it straight off the JVS connectors or through a Capcom I/O off the Jamma edge?

[wonderbanana]

Taking power from the cabs JVS connector.

Just using CN1 (not CN2 though I have this too) since that's all the Capcom IO uses.

Just check whats coming through that first, black/whites your Ground, yellow and red are the +12 and +5, so the black prong to the black/white wire the red prong to the others as shown earlier in the thread.You can even poke the multimeters probes in the back of the connector while its connected up(just don't touch the bare metal on the probes), should be checked under load anyways.I find in my AWSD the JVS power is generally weak rather than too high but who knows.

Many thanks for the help Chop I'll update with findings tomorrow.

Do you use both CN1 and CN2 in your AWSD?

Yeah but i would of thought using just the one would mean less power than both as both's really only needed for the extra ooomph that a GD-rom set up needs i think, carts should run fine off the one i think.
