I have a ryobi p118 tool charger. It stopped working and no lights came on when plugged in without battery. I looked inside and a fuse was blown by the supply. Doesn't seem to be any lose pieces or burned marks so I replaced the fuse with the same specs w/ time delay, brushed off the board and it blew again. Not sure what would cause this. Any ideas?

Beware there Is no fuse inside for repairing used only for fire safety used, on marketing technical base there are no wiring diagrams beware of ordering a separate print of the charger can often be more expensive than a whole new charger and also look first for the option on warranty. powercord problems can a problem but the li-ion chargers are build up mostly with smd components and if damaged there is no support to repair for novice to refurbish.

in the hand book it states that the charging period for new batteries can be up to 6 hours

Yes, the green light flashes until the battery is fully charged on Ryobi chargers. This will change to a solid green light when the battery is fully charged until the charger goes to a power-saving mode. Not all of the Ryobi chargers have a power-saving mode. However, for those that do, the green led will dim over time and then brighten and dim slowly again in this mode.

My Ryobi charger, model P113, actually has a key for the LEDs on the unit on the left of the battery port. The manual for this charger is here: https://manuals.ttigroupna.com/system/files/5495/original/P113_192_trilingual.pdf?2011 . Ryobi has many of their manuals on their site. Look up your charger/tool here: https://www.ryobitools.com/power-tools/support/manuals , Home Depot's web site also has many of these manuals on the product site for the tools that they sell.

I hope this helps.

After looking at the manual for your charger, it looks like most of the Ryobi chargers like the P113, P114, P117, P118 will charge your battery. The connector on the battery looks the same as the P103 and P104 used here in the U.S.

I can answer questions about this charger, but you have not posted a question. Basically if you get a red light when plugged in, it may be functional. You won't know until you try charging a known good battery. You should be able to charge both NiCd and Lithium Ion batteries. If no red light appears when plugged in, a component has failed on the inside. These can only be repaired by a skilled technician with solid state component knowledge and soldering skills. The case is held together by four T20 anti-tamper screws under the four rubber feet. Do not apply power with the cover opened.
Common problems are shorted power rectifier diodes, shorted movistor and opened fuse. If the fuse is not blown check the filter caps by shorting across their leads with a screwdriver. If you can an arc, after the charger has been unplugged for a few minutes, it means the switching regulator has failed. Usually this is a TOP256EN. If it has burned and blew a piece off the regulator, the transformer has probably shorted. If the regulator looks OK, it may work after replacing it. There are many more possibilities, but these are some basics. BTW, this is exactly the same as a Ryobi P113 on the inside except for the battery terminals and the board layout. They have the same components.

yes, most chargers have internal fusses.

Check fuses inside. Check fuse and connections in plug. If this is a 110v radio there is one on transformer winding.
